#1. The polewards moving air piles up in the subtropical regions and forms high pressure belt at the surface, called
#2. ______ occurs over subtropical high
Subsidence is a general term for downward vertical movement of the Earth’s surface
#3. The occurrence of large deserts near 30N and 30S are due to large scale
subtropics are at 30° Lat
subsidence occurs at sub tropics
Subsidence is a general term for downward vertical movement of the Earth’s surface
#4. 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
Check out the diagram for trade winds
#5. The huge vertical circulations, one between the equator and 30N and another between equator and 30S, are called
#6. The descending branch of the Hadley cell marked by calm winds and high pressure at the surface are called
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies.
#7. The winds in the upper troposphere are westerly. These are known as
except in a narrow belt 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 Easterlies.
#8. In the equatorial regions the upper tropospheric winds are
levels. At these levels the temperature gradient is from S to N. Thus, except in a narrow belt 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 Easterlies.
#9. The disturbances of middle latitudes move from
#10. The tropical disturbances which form in the equatorial low pressure belt move in
. The disturbances of middle latitudes move from west to east in the westerly current and the tropical disturbances which form in the equatorial low pressure belt move in a westerly direction, being steered by the high level easterly flow.
#11. Tropical disturbance which reach the zone of transition in the upper level flow change course and begin to move in a
. The disturbances of middle latitudes move from west to east in the westerly current and the tropical disturbances which form in the equatorial low pressure belt move in a westerly direction, being steered by the high level easterly flow.
#12. 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 decreases, so the same amount of solar radiation is spread over a greater surface area. At tropical latitudes however, the sun is directly overhead so the sun’s rays are concentrated on a smaller surface area. The curvature of the Earth also means that incoming solar energy must travel through a greater depth of atmosphere at higher latitudes than at the equator.
#13. 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 has traditionally been concerned with the analysis and prediction of large-scale weather systems, such as extratropical cyclones and their associated fronts and jet streams. An important aim of synoptic training is to acquaint the student with the structure and behavior of the real atmosphere.
#14. Rising air creates calms or doldrums in the equatorial region.
#15. Steady NE winds in the N hemisphere and SE winds in the S hemisphere are called.
