#1. The polewards moving air piles up in the subtropical regions and forms high pressure belt at the surface, called
This high pressure belt near 30° latitude is called the Subtropical High.
#2. ______ occurs over subtropical high
Subsidence, or sinking air, occurs over the subtropical high.
#3. The occurrence of large deserts near 30N and 30S are due to large scale
Deserts occur due to large-scale subsidence which suppresses rainfall.
#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
These are the easterly Trade Winds that blow towards the equator.
#5. The huge vertical circulations, one between the equator and 30N and another between equator and 30S, are called
Hadley Cells are large vertical circulation cells in tropical regions.
#6. The descending branch of the Hadley cell marked by calm winds and high pressure at the surface are called
Horse Latitudes refer to the calm, high-pressure regions at ~30° latitude.
#7. The winds in the upper troposphere are westerly. These are known as
Upper troposphere westerlies are zonal and generally west-to-east.
#8. In the equatorial regions the upper tropospheric winds are
In the equatorial regions, upper tropospheric winds are easterly.
#9. The disturbances of middle latitudes move from
Middle-latitude disturbances move generally from west to east.
#10. The tropical disturbances which form in the equatorial low pressure belt move in
They move generally in easterly direction near the equator.
#11. Tropical disturbance which reach the zone of transition in the upper level flow change course and begin to move in a
They turn and begin to move in the opposite direction due to upper level westerlies.
#12. Latitudinally, on the average there is radiation ______ in the tropics than in the polar regions
The tropics receive a radiation surplus compared to the poles.
#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
The study of weather systems is Synoptic Meteorology.
#14. Rising air creates calms or doldrums in the equatorial region.
The Inter-Tropical Convergence Zone (ITCZ) is a region of rising air and calms.
#15. Steady NE winds in the N hemisphere and SE winds in the S hemisphere are called.
Trade Winds blow steadily NE in N hemisphere and SE in S hemisphere.
