Synoptic Meteorology
Physical Meteorology
3. The tropical disturbances which form in the equatorial low pressure belt move in
Easterly direction
Southerly direction
Westerly direction
4. The descending branch of the Hadley cell marked by calm winds and high pressure at the surface are called
Horse Latitudes
Tropical Latitudes
Middle latitudes
5. ______ occurs over subtropical high
subsidence
convection
advection
6. Tropical disturbance which reach the zone of transition in the upper level flow change course and begin to move in a
