November 29 to December 5 - This week in Denver weather history
November 29 to December 5 - This week in Denver weather history

As always, our look back at Denver’s weather history books is very eventful.  As we start to get closer to winter, we begin to see many more multi-day snow events that are notable and this week’s look is no different.  We see many major snow events and also of note are the damaging high wind events.

From the National Weather Service:

25-29

In 1985…dense fog with visibilities as low as 1/8 mile occurred on five consecutive days at Stapleton International Airport.  The fog was at times accompanied by light snow… Light freezing drizzle…or ice crystals.  Fog occurred all day on both the 26th and 29th.
28-29 in 1908…heavy snowfall overnight and for most of the day on the 29th totaled 12.5 inches.  Precipitation was 1.09 inches.  Northwest winds were sustained to 26 mph on the 29th.
 
In 1928…a major storm dumped 15.5 inches of snowfall on downtown Denver.  North winds were sustained to 18 mph with gusts to 19 mph on the 28th.
 
In 1992…an upper level storm system moved across metro Denver…but left only a dusting of snow.  Snowfall totaled only 1.6 inches at Stapleton International Airport where north winds gusted to 25 mph.  Other snow amounts included: 8 inches at Conifer…6 inches at Lake Eldora…3 inches at Rollinsville and in southeast Denver.
 
In 1997…a storm system tracking across northern New Mexico produced strong north to northeast upslope flow against the eastern slopes of the Front Range and Palmer Ridge. Snowfall totals in Jefferson County included:  14 inches near Deckers; 12 inches at Castle Rock and Sedalia; 10 inches near Conifer…11 miles southwest of Morrison…and at Buffalo Creek.  Elsewhere…snow accumulations were less. Snowfall totaled only 0.7 inch at the site of the former Stapleton International Airport on the 27th and 28th.
 
In 2004…heavy snow fell in the foothills and across metro Denver.  In the foothills…snowfall totals included:  13 inches at Roxborough State Park and Eldorado Springs… 11.5 inches near Conifer…11.0 inches near Nederland…and 10 inches near Indian Hills.  Across metro Denver snowfall totaled 14 inches near Sedalia…9 inches near Louisville… 8 inches at Ralston Reservoir…and 5.1 inches in the Stapleton area of Denver.  Northeast winds gusted to 28 mph at Denver International Airport on the 28th.
 
In 2006…a slow moving storm system brought heavy snow to the mountains and to the eastern foothills where snowfall ranged from 8 to 18 inches.  Some of the more impressive snow totals included:  18 inches at Genesee…17.5 inches near Boulder…17 inches at aspen springs…16.5 inches 10 miles northwest of Golden…15 inches at Eldorado Springs… 14.5 inches in Idaho Springs and near Jamestown…12 inches in grant and near Indian Hills…11.5 inches near Blackhawk… 11 inches at gross reservoir and Eldora…and 10.5 inches in Conifer.  Across metro Denver…storm total snowfall generally ranged from 5 to 9 inches with the heaviest amounts near the foothills in Boulder and Jefferson counties.  The most impressive totals included:  15.5 inches at Ken Caryl…12 inches in Boulder…7.5 inches near Morrison…and 7 inches near both Chatfield and Ralston reservoirs.  Snowfall totaled only 4.2 inches in the Denver Stapleton area.  Northeast winds gusted to 31 mph at Denver International Airport on the 28th.

28-30

In 1991…a winter storm dumped heavy snow in the foothills and near the Palmer Divide with 10 inches recorded at Conifer and Golden Gate Canyon…12 inches in Morrison… 6 inches at Castle Rock and Parker.  Only 3.4 inches of snow fell at Stapleton International Airport where north winds gusting to 35 mph on the 29th…produced some blowing snow.  Some light freezing drizzle also fell on the 28th and 29th.

29   

In 1877…the all-time lowest recorded minimum temperature in the month of November…18 degrees below zero…occurred. The high temperature for the day was 16 degrees.
 
In 1899…northwest winds were sustained to 51 mph with gusts as high as 60 mph.  The Chinook winds warmed the temperature to a maximum of 74 degrees…a record high for the date and the warmest of the month that year.  The minimum temperature was only 39 degrees.
 
In 1927…post-frontal rain changed to snow and totaled 5.8 inches over downtown Denver.  Northeast winds were sustained to 22 mph.
 
In 1977…85 mph winds were reported at Wondervu in the foothills southwest of Boulder.  Northwest winds gusted to 39 mph at Stapleton International Airport.
 
In 1980 strong Chinook winds reached 85 mph in Boulder… Blowing traffic signals and street lights down.  Some windows were shattered by the wind.  West winds gusted to 37 mph at Stapleton International Airport.
 
In 1994…high winds blew across the Front Range eastern foothills.  Wind gusts to 92 mph occurred atop squaw mountain…5 miles south of Idaho Springs…and to 82 mph on fritz peak near Rollinsville in the foothills southwest of Boulder.  A wind gust to 75 mph was recorded at Jefferson County airport near Broomfield.  Northwest winds gusted to only 35 mph at Stapleton International Airport. No damage was reported.

Climategate causes uproar – latest news and opinion

Leave a comment

Late last week thousands of emails from Britain’s top climate research agency were illegally released on the Internet and immediately caused an uproar in the debate about manmade climate change. The messages of private communications between some of the world’s top climate scientists raised questions about possible collusion, manipulation of data, deleting of climate data, and concerted efforts to silence dissenting opinions.

The Climate Change Examiner has been covering the developing story as new information is uncovered. These are some of the more recent stories to have come out:

NASA satellite captures image of Russian volcano’s smoke

NASAs Terra satellite captured this image of a smoke plume coming from the Bezymianny volcano on the the Kamchatka Peninsula in Russia.

The Kamchatka Peninsula in Russia is a relatively active area for volcanic activity, like much of the rest of the Pacific Ring of Fire. The Bezymianny volcano in the east-central part of the peninsula is the smaller of three neighboring volcanoes.

Bezymianny was thought to be extinct until it erupted from 1955 to 1956. Prior to that, it had experienced a period of 1,000 of dormancy. The 1956 eruption was comparable in size to the Mount Saint Helens eruption in 1980 and resulted in a horseshoe shaped crater that has since been filled by other, smaller eruptions and pyroclastic flows.

On Wednesday, Novebmer 25, 2009, NASA’s Terrra spacecraft captured an image of a smoke plume emanating from the volcano. Using the craft’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), the plume is clearly seen as is its shadow.

Skeptic climate scientists’ voices silenced by so-called ‘consensus’

Leave a comment

The unscrupulous efforts of some of the world’s top climate scientists to silence dissent among skeptics is the latest discovery from the Climategate emails that were leaked last week.  Analysis of the messages shows that the scientists colluded together to stifle the opinions of anyone who disagreed with them. 

As the Climate Change Examiner wrote:

Swimming against the tide is never an easy task. Scientists that disagreed with the manmade climate change theory have learned that if you’re swimming against the ‘consensus’ of global warming, it can not only be hard, it can be a nasty business.

For years those who believe other factors beyond man drive the planet’s climate have said they were blocked from publication and been the target of a concerted effort to silence them. Their complaints were largely ignored but with the release of the Climategate documents and emails, the proof shows their claims were not unfounded.

An analysis of the emails from a veritable who’s who in climate science show that some of the world’s top scientists worked directly against dissenting scientists. The scientists worked to discredit other’s work, oust them from professional organizations, exerted pressure on scientific publications and went so far as to consider pushing an educational institution to review the doctorate of a scientist. The moves appear to go far beyond a scientific debate and read more like a vendetta against dissenting opinions.

The story here has all the details and examples how the scientists colluded together in rather disturbing fashion.

England sees record rainfall that brings flooding

Leave a comment
The normally picturesque view of England’s Lake District saw itself become the scene of a rescue operation as helicopters and lifeboats plucked hundreds residents and brought them to safety. The area recorded the most rainfall ever recorded in the nation and the weather was responsible for the death of a local constable.

Widespread heavy rain across England and Ireland caused flooding that brought floods as deep as eight feet and engorged rivers that brought down bridges. England set a national rainfall record when 12.3 inches of rain fell in just 24 hours last week at Seathwaite Farm according to Britain’s Met Office.

In the town of Cockermouth, officials estimate 1,000 homes were flooded and more than 200 people were rescued. Local emergency responders and British soldiers conducted house to house searches to extract those struck by the floods. The town, 300 miles northwest of London, is at the confluence of the Cocker and Derwent rivers and is the birthplaces of poet William Woodsworth.

November 22 to November 28 - This week in Denver weather history
November 22 to November 28 - This week in Denver weather history

This time period in November has been exceedingly eventful throughout Denver weather history.  Notable as usual are big wind events that have caused damage and injuries.  Snow of course is also quite present, including the Thanksgiving blizzard of 1983 which dumped an astounding 21.5 inches of snow on the Mile High City. 

From the National Weather Service:

21-22

In 1905…a trace of snow fell on both days in downtown Denver.  This was the only snow of the month…ranking the month along with other Novembers…the 2nd least snowiest on record.
 
In 1999…the first significant snowfall of the season struck metro Denver.  Snowfall totals included:  16 inches near bailey; 13 inches near evergreen; 12 inches at north turkey creek…Genesee…near Morrison…and near Sedalia; 11 inches near Conifer and in evergreen; 10 inches in Louisville; 9 inches in Brighton…Broomfield…and Denver; and 8 inches at Arvada…Castle Rock…and Eldorado Springs.  Snowfall totaled 8.4 inches at the site of the former Stapleton International Airport.
 
In 2003…heavy snow fell in and near the foothills of Boulder County.  Snowfall totaled 10.5 inches in Eldorado Springs. Across the city…snowfall was lighter with 2.8 inches measured at the site of the former Stapleton International Airport on the 22nd.  North winds gusted to 32 mph at Denver International Airport on the 22nd.

21-23

In 1918…post-frontal snowfall totaled 5.9 inches in downtown Denver.  Most of the snow…5.3 inches…fell on the 22nd. North winds were sustained to 20 mph on the 21st.
 
In 1931…a major storm dumped a total of 13.2 inches of snowfall over downtown Denver.  Most of the snow…11.4 inches…fell on the 21st.  A very cold air mass settled over the city after the heavy snow on the 21st.  After a low temperature of zero…the temperature climbed to a high of only 5 degrees on the 22nd…a record low maximum for the date.

21-25

In 1952…snowfall of 6.2 inches was measured at Stapleton Airport where northeast winds gusted to 17 mph on the 21st.

22

In 1977…101 mph winds were measured in southwest Boulder. The side of a garage was blown down.  West winds gusted to only 33 mph at Stapleton International Airport.
 
In 1981…high winds occurred in the foothills.  A peak gust to 75 mph was reported at Wondervu.  West winds gusted to 23 mph at Stapleton International Airport.
 
In 1988…a wind gust to 88 mph was measured at Rollinsville.
 
In 1990…strong west to northwest winds…on the coat tails of a mountain snow storm the day before…lashed out at portions of the eastern foothills with 60 to 95 mph wind gusts.  The strong winds spread over all of metro Denver. A west wind gust to 49 mph was recorded at Stapleton International Airport.

The great coverup – Did a hacker expose a climate science conspiracy?

Leave a comment
Hackers may have exposed a concerted effort by the world's leading climate scientists to coverup and delete climate data.
Hackers may have exposed a concerted effort by the world's leading climate scientists to coverup and delete climate data.

Skeptics of manmade climate change may very well have found their Holy Grail.  A hacker apparently broke into the computer systems of the UK’s Hadley Climate Research Unit and made off with over 1,000 emails and dozens of files.  The contents of the archive, if proven to be authentic, would expose nothing less than a conspiracy amongst some of the world’s leading climate scientists.

As told on the Climate Change Examiner, the emails detail discussions taking place that include the modification of climate data, preventing access to data by those who disagree, deleting data that does not fit the global warming theory and so much more.  This would be nothing less than one of the biggest scandals to have EVER occurred in science.

ClimateGate – Climate center’s server hacked revealing documents and emails

Britain’s Climate Research Unit, University of East Anglia, suffered a data breach in recent days when a hacker apparently broke into their system and made away with thousands of emails and documents. The stolen data was then posted to a Russian server and has quickly made the rounds among climate skeptics. The documents within the archive, if proven to be authentic, would at best be embarrassing for many prominent climate researchers and at worst, damning.

…

The contents of the archive contain documents and email correspondence from a veritable who’s who in climate science. Among those included in the emails are Phil Jones, Keith Briffa, his assistant, Michael Mann of the University of Virginia, Malcolm Hughes at the University of Arizona, Kevin Trenberth at the National Center for Atmospheric Research, James Hansen of NASA’s Goddard Institute of Space Studies and others.

The emails contain an array of discussions including what appear to be concerted efforts to withhold data. Just as troubling is conversations that allude to potentially manipulating climate data to “hide the decline” of temperatures seen in the last decade.

Dissent about climate change theory highlighted in survey of weathercasters

Leave a comment

In a recent survey by the American Meteorlogical Society, 50% of TV weathercasters disagree that man is responsible for global warming.
In a recent survey by the American Meteorlogical Society, 50% of TV weathercasters disagree that man is responsible for global warming.

The American Meteorological Society released the results of a survey of TV meteorologists gauging their opinions on climate change. With a full 50% of respondents disagreeing that man is responsible for global warming, the survey indicates continuing cracking in the ‘consensus’ of the manmade climate change theory.

The survey results, published in the October 2009 issue of “Bulletin of the American Meteorological Society” (BAMS), show that a significant portion of meteorologists continue to doubt that man is the driving force of climate change. When asked about the UN’s Intergovernmental Panel on Climate Change’s (IPCC) statement that “Most of the warming since 1950 is very likely human-induced,” a full 50% either disagree or strongly disagree. 25% were neutral and a mere 24% said they agreed or strongly agreed.

Similarly, meteorologists doubt the very global climate models on which the anthropogenic global warming theory is based. These models have been shown to be incapable of predicting historical climate changes and their predictions continue to fall outside of scientific norms. Reflecting this, 52% of the meteorologists disagreed with that statement that “Global climate models are reliable in their projections for a warming of the planet.” A mere 19% said they agreed with the statement.

Respondents also showed an apparent distrust of many current sources of climate related information. The weathercasters said they wanted “to have access to “independent,” “unbiased,” and “reputable” sources of data and information that present “both sides” of the issue.”

World leaders give up on Copenhagen climate treaty

Leave a comment
Faced with the reality that many nations are unwilling to commit to an agreement, world leaders said yesterday that a global climate change treaty will not become reality next month. Heads of state, assembled in Singapore for the Asia Pacific Economic Cooperation forum (APEC), said the United Nations Climate Conference (COP 15) in Copenhagen, Denmark will instead be used to further the discussion about global warming.

Two years of labor going into the COP 15 conference will be for naught and at best could yield a political agreement but not a legally binding treaty. A large gap between developing nations and richer countries continues to prevent an agreement.

Developing nations including India, Brazil and China have insisted on billions of dollars in international aid and said that any goals should be just that and not requirements. Nations like the United States however have been reluctant to agree to any deal that did not require all nations to legally comply with emissions restrictions.
