markedly in February (fig. 1) as their core moved south of normal in the eastern Pacific Ocean and north of normal over the Atlantic Ocean (fig. 2). The net result was a blunt profile of zonal wind with little variation of mean wind speed from 25 ’ to 60°N (fig. 1). The mean wind speed at 700 mb was weaker than normal from 30 ° to 45ON and stronger than normal both to the north and south. February’s deep Kamchatka trough brought strengthened northwesterly flow over the Sea of Qkhotsk (figs. 3, 4). The intensified thermal gradients over the western Pacific provided an ample source of available potential energy that apparently contributed, through eddy conversion processes, to the stronger than normal westerlies observed from China to the Mexican coast. The greatest 700-mb wind speed anomaly in the hemisphere
