Recent climate change in North America and CO/sub 2/: Search in stratified daily data: Progress report for period 4/31/86-4/31/87
The objectives were: (1) to identify the CO/sub 2/ fingerprint in stratified daily weather records available since 1900; (2) to characterize recent climate fluctuations in North America in terms of the changing frequency and distribution of various daily weather types; and (3) to determine empirical relationships of humidity, cloud cover, wind, precipitation, snow, etc., to surface air temperature and to use this information for improvements of the input to climate models. The results indicate: (1) a relative warming of urban sites with respect to the countryside; (2) a significant decrease of the diurnal temperature range has taken place; (3) an increase of minimum temperatures under overcast skies; and (4) an increase in both minima and maxima under clear skies.
