TWO DAYS. A JET EXTENDS FROM THE N END OF THE CIRCULATION NEAR 
26N140W TO 32N130W TO BEYOND 32N115W. A LARGE AREA OF 
SOUTHWESTERLY TO WESTERLY FLOW ALOFT COVERS THE AREA S OF THE 
JET TO 20N AND BECOMES MORE SOUTHERLY TO SOUTHWESTERLY S OF 20N 
TO 10N W OF 120W. INFRARED SATELLITE IMAGERY DISPLAYS A LARGE
