Regulations#1. ______ occurs over subtropical high
Subsidence is a general term for the downward vertical movement of the Earth’s surface.
#2. The huge vertical circulations, one between the equator and 30N and another between equator and 30S, are called
#3. The tropical disturbances which form in the equatorial low pressure belt move in
Mid-latitude disturbances move from west to east within the westerly current, while tropical disturbances that form in the equatorial low-pressure belt move westward, guided by the eastward flow at higher altitudes.
#4. Tropical disturbance which reach the zone of transition in the upper level flow change course and begin to move in a
Mid-latitude disturbances generally move from west to east within the westerly current, while tropical disturbances that form in the equatorial low-pressure belt tend to move westward, guided by the eastward flow at higher altitudes.
#5. Rising air creates calms or doldrums in the equatorial region.
#6. The disturbances of middle latitudes move from
#7. The winds in the upper troposphere are westerly. These are known as
Except for a narrow band near the equator, the winds in the upper troposphere are westerly, known as the zonal westerlies. In the equatorial regions, the upper tropospheric winds are easterly.
#8. Steady NE winds in the N hemisphere and SE winds in the S hemisphere are called.
#9. The descending branch of the Hadley cell marked by calm winds and high pressure at the surface are called
The horse latitudes are located approximately 30 degrees north and south of the equator. They are characterized by clear skies, calm winds, and minimal precipitation. These regions are also known as subtropical ridges or highs, representing areas of high pressure where trade winds and westerlies diverge.
#10. In the equatorial regions the upper tropospheric winds are
At these altitudes, the temperature gradient is from south to north. As a result, except for a narrow band near the equator, the winds in the upper troposphere are westerly, known as the zonal westerlies. In the equatorial regions, the upper tropospheric winds are easterly.
#11. Latitudinally, on the average there is radiation ______ in the tropics than in the polar regions
At the poles, the Sun’s angle in the sky is lower, spreading the same amount of solar radiation over a larger area. Near the equator, however, the Sun is directly overhead, concentrating its rays on a smaller area. The Earth’s curvature also means that incoming solar energy must pass through a thicker layer of atmosphere at higher latitudes compared to the equator.
#12. The occurrence of large deserts near 30N and 30S are due to large scale
Subtropics: The subtropics are generally located between 30° and 40° latitude north and south of the equator.
Subsidence: Subsidence is a meteorological term referring to the downward vertical movement of air. It often occurs in subtropical regions due to the circulation patterns of the atmosphere.
#13. A part of the sinking air over the subtropical high flows towards the equator, turning west (in the northern hemisphere) due to the Coriolis force. This surface air is called
#14. The systems like highs, lows, cyclonic circulation etc are associated with distinct types of weather. A study of the behaviour of these systems, known as
Synoptic meteorology traditionally focuses on analyzing and predicting large-scale weather systems, such as extratropical cyclones, their associated fronts, and jet streams. A key goal of synoptic training is to familiarize students with the structure and behavior of the real atmosphere.
#15. The polewards moving air piles up in the subtropical regions and forms high pressure belt at the surface, called
