| Abstract: | Analysis is done of the divergence component of the monthlymean wind field at 850 hPa for a period of roughly 10 years. Resultsshow that three convergent and three divergent zones are observed inthe monthly climatic velocity potential fields for each of the fourseasons with marked seasonal change occurring over the South-AsianPlateau, South America and Africa and slight variation taking place inthe Eastern Indian Ocean and the low-latitude Pacific. The interannualanomalies of these divergent wind fields are found to bear a close relationwith E1 Nino/anti-E1 Nino events. During the 1982--1983 E1 Nino episode,for instance, the wind field shows an anomalous process associated with it. |
