The Occurrence of Anomalous Winds and Their Significance

Observational evidence is provided for t,he occurrence of anomalons winds which represent it11 anticyclonic rotation in space, and a mechanism for their development is suggested. Thc unstable natnre of these winds and the role they play in the development of certain types of atmospheric disturhmces is then discussed, and it is suggested that anomalous winds provide the dynamic mechanism for triggering hurricane formation and for the observed deepening of troughs downstream from intense pressure ridges. Finally it is noted that although the Observational evidence presented is for the occurrence of anomalons winds over small regions of the atmosphcrc, their development is dependent on large-scale processes and their effect cxtcnds beyond the area where they occur.
