Description:
The cloud structure of an occluded cyclone and its environs over the Gulf of Alaska is revealed in detail by a series of TIROS pictures. The pictures clearly portray:(1) the nature and extent of dense cloudiness around the inner core of the cyclone;(2) a broad band of cloudiness associated with the main polar front;(3) the pattern of overrunning cloudiness marking a newly developing wave south of the main storm;(4) a previously undetected, old cyclonic vortex in mid-troposphere; and(5) the striking cellular arrangement of cumuliform clouds in the cyclonic flow to the rear of the storm. These features are related to the conventional meteorological data and analyses over this area and are found in many places to corroborate them rather well. On the other hand, there are several places, particularly in view of the sparsity of conventional data, where the cloud pictures suggest that improvements could be made in the map analyses and numerically computed vertical motions on the basis of the TIROS cloud information.
