                         Methods: First to SPL and after other variables: get the 
                         differrentiated series deltaSPL = SPL (t+1) \− SPL (t); SPL 
                         will be in phase increase is deltaSPL is positive, in contrast SPL 
                         will be in phase decrease if deltaSPL is negative, i.e., increase 
                         (or decrease) trends in sea level pressure averaged over a 
                         one\−month M window time. To quantify the changes in 
                         spatial difference will use r(m,d), r(d) season metric (ave: Feb., 
                         Mar., Apr., May.), were used too r(m,s) to drougth period. As
