Updating statewide monthly temperature extremes
I did not change my information because the NOAA daily records did not verify the change in the monthly records... As far as I can tell, the historical data for these records have not been adjusted upward or downward as has some analytical data used to show an upward trend increase recently... Just this week, NWS threw out what would have been an all-time state record for Illinois based on NWS citing lack of confidence in equipment, claiming “ASOS better than AWOS”. The lowest annual value was 11.0°C in 1912 whereas the warmest was 14.2°C in 1934.The 2013 CONUS average temperature was 2.9°F cooler than the 2012 average temperature, which was the warmest year on record for the nation.Since 1895, when national temperature records began, the CONUS has observed a long-term temperature increase of about 0.13°F per decade. The statewide average annual temperature is 12.4°C. Bats threatened by climate change, and may boost frog disease chytridiomycosis. Statewide average temperatures range from -1.6°C in January to 26°C in July (Figure 1).So that you understand what this is about, a few years ago I was looking for evidence of global warming based on the assertion that such warming would be manifested by more extreme high temperatures. What it also showed, however, was that the 1930s had a much higher frequency of those records.An analysis of our local temperatures revealed that most of the records occurred in the 1950s and 1980s, not in the last 20 years. Finally, it showed a sharp tailing off of such extremes beginning with the new century.
Average annual precipitation is approximately 45” statewide. One of premises of global warming theory is that: These charts summarize the annual number of new monthly, statewide records.There is a limit of 600 maximum and 600 minimum records for this data set... New records are set and replace old records if the temperature . The file has several worksheet tabs at the bottom of the screen.Inter-annual variability is large; with 1054 mm in 1951 whereas 391 mm was the lowest annual precipitation amount in 1956.The State of Delaware lies along the Atlantic coast of the United States, occupying the northern two-thirds of the Delmarva Peninsula.
