Question : 36 [SSC HSLDEO 2010]
The vertical movement of air is termed as
a) air current
b) wind
c) air mobility
d) air turbulence
Answer »Answer: (a)
An updraught or downdraught is the vertical movement of air as a weather-related phenomenon. Better known as air current, they can be caused by differences in temperature, pressure, or impurity concentration.
Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear 'lighter.' Rising air is associated with turbulence as it creates low pressure on the surface.
Question : 38 [SSC CGL Pre 2004]
Convectional Rainfall occurs in:
a) Temperate region
b) Equatorial region
c) Polar region
d) Tropical region
Answer »Answer: (b)
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is an almost daily occurrence and even distribution of rain, and temperate areas in summer.
It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.
