Observed Number of Very Warm Nights
Figure 1.2bNorth Carolina State University
Kenneth E. Kunkel
The observed (a) number of very hot days (annual number of days with maximum temperature at or above 95°F), (b) number of very warm nights (annual number of days with minimum temperature at or above 75°F), (c) annual precipitation, and (d) total number of hurricanes affecting Alabama, averaged over 5-year periods (bars; last bar represents 4-year average). Filled circles connected by black line segments show annual values. The horizontal black line shows the long-term average. The values in Figures 4a and 4b are averages from long-term reporting stations, nine for temperature and eleven for precipitation. The values in Figure 4c are from NCEI’s version 2 climate division dataset. Very hot days and very warm nights have generally been below average in recent decades. Since the 2000s, annual average precipitation has been close to the long-term average; however there has been high year-to-year variability and this period includes the 2nd driest year on record (2007) and the 3rd wettest (2009). There is no overall long-term trend in the number of hurricane events; since 2000 the state has been impacted by four storms. Source: CICS-NC and NOAA NCEI.
