Definition: When there is a high altitude due to cooling due to heat loss in some places, the exiting wind flows from the high pressure center to the lower depression region. It is called anti-cyclone.
Location: Originally formed in the frozen and temperate regions, if there is favorable change in regional characteristics, then it may be created in any region of the world. Note: In the winter, there is a reverse revolution in the northern part of the United States of America and the snow-covered region of Canada.
Features: Rectangal whirlpools are as follows -
A) Wind tension: Proximate cyclone center has high pressure.
B) The direction of the flow: It flows in the northern hemisphere on the right and in the southern hemisphere.
C) Wind: Its wind is cold, outgoing and downward.
D) Duration of origin: the actual period of its origin is winter
E) Stability: It is a kind of chronic atmospheric condition.
F) Wind speed: The speed of the rectangular whirlwind velocity is 30 - 50 km / h, ie, less than that.
G) Weather: It prevents the calm cloud-free weather in the exposed areas. Although there is no rain in the sky due to cloudy sky, there may be occasional snowfall in the region.
