Question

During cyclone air moves from:
(A) Region of high pressure to low pressure
(B) Region of high pressure to high pressure
(C) Region of low velocity to high velocity
(D) Region of high pressure to low velocity

Answer 1

Hint: When there is a difference in atmospheric pressure, air moves from the higher to the lower pressure area, resulting in winds of various speeds. Cyclones are characterized by inward spiralling winds that rotate about a zone of low pressure.

Complete Step by Step Solution
In a cyclone the central air pressure is lower than that of the surrounding environment. In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are also characterized by low-level convergence and ascending air within the system. Thus, during a cyclone air moves from regions of high pressure to low pressure.
An anticyclone is a system of winds that rotates around a center of high atmospheric pressure.
Option A is the correct answer.

Note
The flow of circulation is clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere. The largest low-pressure systems are polar vortices and extra-tropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and intensification. Extratropical cyclones begin as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract and form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, extratropical cyclones occlude as cold air masses undercut the warmer air and become cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the subtropical jet stream.
