Strong El Niño events impact the spring precipitation across southeast New Mexico, resulting in 100% to 132% of the long term average precipitation. However, there is a significant decrease from DJF precipitation for strong El Niño's (ranging from 177% to 239% of normal). Results for Climate Division 7  indicate that 1992 was an unusually wet year for Roswell and likewise for 2007 in Carlsbad.

 

A description of the graphs is located at the bottom of the page.

Precipitation values for 3-month periods during 18 El Niño Events since 1949-50 are plotted with respect to the long term precipitation average, listed to the right of the graph.  The precipitation totals for each 3-month period are plotted above or below each bar.  Years for which the El Niño Event was considered to be strong are colored in dark green.  "M" represents a 3-month period with missing data. Finally, the percents of long term normal for all El Niño events and for the strong El Niño events are listed below each graph.
