Regions of Enhanced Sensitivity Due to
Recent Seasonal Climate Variability
 
 
| The map above has been generated from the 9-month WASP Index (Weighted Anomaly Standardized Precipitation) for the period September 2003 to May 2004.
Green-shaded regions indicate
unusually wet conditions over this 9-month period, while brown areas have been unusually dry.  
Both
indicate areas with increased sensitivity to future
climate and societal stresses. | 
3 Month Precipitation Persistence 
 
 
| 
Areas colored in brown (green) indicate regions where 
monthly rainfall was in the bottom (top) 20% of the (1979-present) 
observational record with lighter (darker) shading indicating where 
this condition was met for two (three) of the past three months. 
Contours are climatological precipitation for 
the period in cm per month.

3 Month Temperature Persistence 
 
 
| Areas colored in blue (red) indicate regions where 
monthly temperature was in the bottom (top) 20% of the observational 
record with lighter (darker) shading indicating where this condition 
was met for two (three) of the past three months.
