Meaning of Anticyclone
What is Anticyclone:
An anticyclone is the region whose atmospheric pressure is greater than that of the air around it.
The anticyclone is a meteorological phenomenon that generates good weather with clear skies, either with cold days or hot days, and rarely occurs with mist or fog.
This is possible because the air of the anticyclone descends from the highest layers of the atmosphere to the ground, which prevents clouds or rain from forming. This air descends forming a small constant angle or curve, which can be traced on a weather map.
Now, the anticyclones that occur in the northern hemisphere are characterized by the fact that the air circulates in the same direction as clockwise, but in the southern hemisphere the air circulates in the opposite direction.
Types of anticyclone
There are two types of anticyclone according to their behavior and temperatures.
Thermal anticyclone: it is an anticyclone in which an air mass descends because it is colder than that of its surroundings. That is, the air descends due to cooling, which increases the atmospheric pressure and reduces the temperatures in the lower atmospheric layers. The result is a sunny, dry and cold day.
Dynamic anticyclone: in this anticyclone the air mass descends as a result of it being pushed towards the ground when cold air collides with tropical air at altitude. The result is a clear, dry, sunny and hot day.
On the other hand, it is worth mentioning the Azores anticyclone, which is a dynamic anticyclone located in the center of the North Atlantic. This anticyclone determines, both in Portugal and in Spain, the hot, dry and sunny days in the summer season.
Difference between anticyclone and cyclone
As previously stated, the anticyclone is a region of the earth's surface whose atmospheric pressure is greater than that of the surrounding air. On the contrary, a cyclone is the meteorological phenomenon that occurs in regions whose atmospheric pressure or storm is lower than the air around it.
Cyclones are characterized by causing a large accumulation of clouds, strong winds, storms, rains and low temperatures due to the scarce passage of sunlight to the earth's surface.
Cyclones acquire more energy from the condensation of humid air, hence they are responsible for the formation of hurricanes, typhoons and tropical storms.
