Answers
Answer:
Heavy and prolonged rains due to cyclones may cause river floods and submergence of low lying areas by rain causing loss of life and property.
Cloudy days are warmer than cloudless days because: The clouds in the climate go about as a hindrance from heat. In the event that the sky is clear the warmth transmitted from the earth's surface will escape without difficulty into the upper skies or space bringing about the cooler temperature.
Fog creates dangerous driving conditions and has been the cause of a high number of accidents and fatalities. Fog is a cloud form at the surface of the earth made of tiny water droplets suspended in the air. The greatest problem with fog is visibility. ... Slow down and do not drive faster than your vision.
Answer. Convectional rainfall is also called 4 o 'clock rain: Convectional rainfall is the result of high rate of evaporation. Then condensation takes place and rain falls. At mid day , when the sun is at the highest position, the temperatures rise at the equator.
Polar easterlies are cold and dry winds coming from polar highs of North and South poles towards low-pressure Westerlies at high latitudes. Cold air from the poles moves out causing a high pressure in the area and as a result, equatorward outflow of air takes place which gets deflected towards west by Coriolis effect.
