Cold air pouring in behind yesterday's remarkable snowstorm over northeast Oklahoma has brought unprecedented cold to the state this morning, with a bone-chilling -31°F recorded at Nowata and -28°F at Bartlesville. These are the coldest temperatures ever measured in Oklahoma. According to Extreme Weather, the excellent weather records book by wunderground's weather historian, Christopher C. Burt, the previous coldest temperature in Oklahoma was -27°F set in nearby Watts on January 18, 1930. A personal weather station in nearby Hogshooter Valley also hit -28°F this morning (one wonders how the Valley got its colorful name!) Today's record is the second time since the year 2000 that one of the 50 states has set an all-time extreme cold temperature record. On January 16, 2009, Big Black River, Maine set a new state record with -50°F. In comparison, three states--Virginia, California, and South Dakota--have set all-time extreme heat records since 2000. Since 1990, nine states have set all-time extreme high temperature records, and eight states have set all-time extreme cold records. It was also very cold in Arkansas this morning, with a -20°F reading in Springdale. The all-time coldest temperature for Arkansas is -29°F, recorded on February 13, 1905, at Pond and Gavette. Relief is in sight, though--Tuesday's forecast calls for high temperatures in Bartlesville in the low 60s, a full 90 degrees warmer than this morning's low!

Yesterday's major snowstorm blasted northeast Oklahoma, northwest Arkansas, and southwest Missouri with up to two feet of snow. The heaviest snows fell in northeast Oklahoma, with 25 inches reported at Jay. Siloam Springs in northwest Arkansas had 24.5", which is just 1/2" shy of the Arkansas state record for heaviest snowstorm of all-time, the 25" that fell on Corning on January 22, 1918. Yesterday's storm brought heavy snows of a foot or more to Kansas, Texas, Missouri, New Mexico, Colorado, Montana, and Wyoming, according the the latest NOAA Storm Summary. Significant snows also hit much of the Southeast, with 4.5" recorded in Vernon, AL; 3.8" in Memphis, TN; 3.7" in Bowling Green, KY; and 1" in Asheville, NC. The snow has almost ended over the Southeast, as the storm is now centered off the North Carolina coast and is moving out to sea.

Snowiest month and year in Tulsa's history
The 6.2 inches of snow that fell in Tulsa, Oklahoma during yesterday's snowstorm gave that city its snowiest month on record, according to the National Weather Service. Tulsa has received 23" of snow this month, most of this in the February 1 blizzard. The previous record snowiest month was March 1924, when 19.7" fell. The total for the 2010 - 2011 season now stands at 26.6", a new record. The previous record was the 25.6" that fell in the winter of 1923 - 1924. Oklahoma City received 5.9" of snow, bringing their seasonal total to 19.6", still well shy of their all-time record of 25.2", set in 1947 - 1948.

Quoting RyanFSU:
With regards to the linkage between tropical cyclone activity and climate change: the current scientific consensus is the following (Knutson et al. 2010):

"In terms of global tropical cyclone frequency, it was concluded that there was no significant change in global tropical storm or hurricane numbers from 1970 to 2004, nor any significant change in hurricane numbers for any individual basin over that period, except for the Atlantic (discussed above)."

This is shown clearly in Webster et al. 05 plots, as well as my updated version on my website.

"Thus, considering available observational studies, and after accounting for potential errors arising from past changes in observing capabilities, it remains uncertain whether past changes in tropical cyclone frequency have exceeded the variability expected through natural causes."

"The short time period of the data does not allow any definitive statements regarding separation of anthropogenic changes from natural decadal variability or the existence of longer-term trends and possible links to greenhouse warming. Furthermore, intensity changes may result from a systematic change in storm duration, which is another route by which the storm environment can affect intensity that has not been studied extensively."

". . . we cannot at this time conclusively identify anthropogenic signals in past tropical cyclone data."


Thanks for that paper Dr. Maue.

Yeah, some are still wondering where they can find the GOES archives of the Rainbow Floater for Hurricane Camile. They swear there was one though.


And you can get some images of Camille, but precious few and very poor quality, certainly not full temporal coverage.

Somethings wrong with either a) the articles calculations or b) the graph Levi32 posted.

I'm getting a difference of about 90 cat 4+5 cyclones between adding up the stats from this table from the article in science in 2005:

Basin 1975–1989 1990–2004
Number Percentage Number Percentage
East Pacific Ocean 36 25 49 35
West Pacific Ocean 85 25 116 41
North Atlantic 16 20 25 25
Southwestern Pacific 10 12 22 28
North Indian 1 8 7 25
South Indian 23 18 50 34
Table 1.

Change in the number and percentage of hurricanes in categories 4 and 5 for the 15-year periods 1975–1989 and 1990–2004 for the different ocean basins.

and adding up the cyclone bars on Levi32's graph (which was 179). Adding up the numbers from the table gives 269.

Don't know which one is correct, but that explains the discrepancies in the avg. of 12,6 and 18.

Global Climate Change Indicators
National Oceanic and Atmospheric Administration
National Climatic Data Center



Many lines of scientific evidence show the Earth's climate is changing. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming. It is worth noting that increasing global temperature is only one element of observed global climate change. Precipitation patterns are also changing; storms and other extremes are changing as well.
How do we know the Earth's climate is warming?

Thousands of land and ocean temperature measurements are recorded each day around the globe. This includes measurements from climate reference stations, weather stations, ships, buoys and autonomous gliders in the oceans. These surface measurements are also supplemented with satellite measurements. These measurements are processed, examined for random and systematic errors, and then finally combined to produce a time series of global average temperature change. A number of agencies around the world have produced datasets of global-scale changes in surface temperature using different techniques to process the data and remove measurement errors that could lead to false interpretations of temperature trends. The warming trend that is apparent in all of the independent methods of calculating global temperature change is also confirmed by other independent observations, such as the melting of mountain glaciers on every continent, reductions in the extent of snow cover, earlier blooming of plants in spring, a shorter ice season on lakes and rivers, ocean heat content, reduced arctic sea ice, and rising sea levels.

Me tinks some May need some more time to garner the proper perspective on when we started the Satellite Obs.

TIROS I (or TIROS-1) was the first successful weather satellite, and the first of a series of Television Infrared Observation Satellites. It was launched at 6:40 AM EST[1] on April 1, 1960 from Cape Canaveral, Florida, in the United States.

Right, and so therefore the first ever satellite must have had full coverage of the earth continuously forever and ever afterwards with Dvorak intensity estimations for TCs, right?

No. A quick look at the NOAA Satellite Archive will show that a sufficient number of satellite images covering the majority of the globe did not begin until 1978. Before that it was all testing and sporadic data.

Quoting JFLORIDA:
Denial is like a broken record - while they still are quoting the same studies and blogger issues - research has moved on to location specific analysis as obviously cyclone development and intensity isn't a uniform occurrence over the globe and across weather and climate patterns.

What Has Changed the Proportion of Intense Hurricanes in the Last 30 Years?


I dont come here to see dated denial repeated day in and out by those proved wrong time and time again.

Its not warming - its the sun - co2 isn't increasing - its not man made - it volcanoes - etc... the checklist of incorrect climate wishcasting grows perpetually.

Ill get my information from experts, thank you.


It was your esteemed colleague who posted a study which had false information in it. You should be reprimanding him instead and commending us for exposing the bad data by citing the real stuff.

Again, are you guys really going to argue with the international tropical cyclone record data base which is also kept by NOAA.

One of the best titles for a scientific paper has to be the Ig Nobel prize winning "Unskilled and unaware of it: How difficulties in recognizing one's own incompetence lead to inflated self-assessments".

The paper compares people's skill levels to their own assessment of their abilities. In hindsight, the result seems self-evident. Unskilled people lack the skill to rate their own level of competence. This leads to the unfortunate result that unskilled people rate themselves higher than more competent people. The phenomenon is known as the Dunning-Kruger effect, named after the paper's authors, and is often seen in the climate debate.

There are many with a cursory understanding who believe they're discovered fundamental flaws in climate science that have somehow been overlooked or ignored by climate scientists. Some take this a step further and believe they're being deceived. Link


NOAA isn't incompetent with keeping TC records, so go discuss it with them if you have a problem. The numbers from that study were flat wrong based on international consensus. I also don't consider myself incompetent enough to be unable to create a graph from exactly 33 data values.

Sorry, you gotta pay to read the whole thing :)

Chylek, P., and G. Lesins (2008), Multi-decadal variability of Atlantic hurricane activity: 1851-2007, J. Geophys. Res., doi:10.1029/2008JD010036

abstract

“An analysis of Atlantic hurricane data (HURDAT), using a hurricane activity index that integrates over hurricane numbers, durations and strengths during the years 1851-2007, suggests a quasi-periodic behavior with a period around 60 years superimposed upon a linearly increasing background. The linearly increasing background is significantly reduced or removed when various corrections were applied for hurricane under-counting in the early portion of the record. The periodic-like behavior is persistent in uncorrected HURDAT data as well as in data corrected for possible missing storms. The record contains two complete cycles: 1860-1920 and 1920-1980. The 2004 and 2005 hurricane seasons were unusual in that two intense hurricane seasons occurred in consecutive years. The probability for this happening in any given year is estimated to be less then 1%. Comparing the last 28 years (1980-2007) with the preceding 28 years (1953-1980) we find a modest increase in the number of minor hurricanes (category 1 and 2), however, we find no increase in the number of major hurricanes (category 3-5). The hurricane activity index is found to be highly correlated with the Atlantic Multi-decadal Mode (AMM).”

Hurricanes Are Getting Stronger, Study Says Link


Alright, now I really do wonder where this crud comes from. Here are some quotes from that article:

"The number of Category 4 and 5 hurricanes worldwide has nearly doubled over the past 35 years, even though the total number of hurricanes has dropped since the 1990s, according to a study by researchers at the Georgia Institute of Technology and the National Center for Atmospheric Research (NCAR). "

""What we found was rather astonishing," said Webster. "In the 1970s, there was an average of about 10 Category 4 and 5 hurricanes per year globally. Since 1990, the number of Category 4 and 5 hurricanes has almost doubled, averaging 18 per year globally.""

Ok so point #1: Based on best-track data, their statement that the average number of Cat 4-5 tropical cyclones globally was about 10 per year in the 1970s seems to check out (but only based on the late 1970s with satellite observation). However, saying that the average since the 1990s is 18 per year is complete bologna, as the average is actually 12.6.



Point #2: Although the data set since 1978 shows a slight increase in the global number of Category 4-5 tropical cyclones, it is a very short time-scale since we have had satellite observation, and the variations are easily explained. In the late 1970s we came out of a cold PDO when the equatorial waters were much colder, and they were warming all through the 1980s and 1990s with dominant El Ninos. These warmed the central Pacific and allowed typhoons much more time to attain high category intensity. This is a very well-known correlation.

Near 2000 there was a dip, and then another peak in the middle of last decade, but the trend has been pretty flat since the 1990s when the warm PDO phase reached maturity in the Pacific. There is no significant trend independent from natural cycles, and certainly not anything as grossly exaggerated as that study claims.

Not only that, but I would love to know where the data for the left half of this graph (the first one below) came from in the first place, because best-track data from tropical cyclone centers all over the world show a negligible trend in Category 3, 4, and 5 cyclones over the last 30 years (2nd graph).

Yep, BS.

We only know the peak intensity of TCs from the amazing scatterometer pass (almost never), flight level assumed reductions (but only in one basin, mostly, and peak of TC must happen when HHs present and in right place), or SFMR on HHs (same caveats as the previous), or, lastly, Dvorak method (depends entirely on visible satellite, which was not available for most of the globe until recently).

Globally, the observation systems aren't homogeneous, nor has any one basin had the same observation type and frequency for the last 30 years. How many hurricanes have their peak intensity AT landfall in the last 15 years? 1? Anyone would agree that such a thing is rare. How many had their peak intensity AT landfall before 15 years ago? Many.
Did the TCs change? Or did our observations of them change?

Thus, it must be assumed that most TCs' peak intensity occurred before they were observed, at landfall. And the numbers of higher category TCs in these plots is too low.
