Answers
Answer:
1.
(1) Winds are generated due to heating of earth.
(2) Windmill anemometer is the instrument used to tell the direction of wind.
(3) In the southern Indian Ocean or the South Pacific, they are called tropical cyclones or severe tropical cyclones. In the Bay of Bengal or Arabian Sea, both in the northern Indian Ocean, they are simply called cyclones.
(4) The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 kilometers (19–40 miles) in diameter
(5) Air expands on heating and contracts cooling.
2.
(1) Thunderstorm, a violent, short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong, gusty winds.
Unstable air forms when warm, moist air is near the ground and cold, dry air is up above. To create a thunderstorm, the unstable air needs to have a nudge upward. This lift usually comes from differences in air density. Warmer, less dense air rises upward, creating lift.
(2)A lightning strike generates a huge amount of electric charge. The lightning bolt has a temperature of about 30000 degree Celsius. ... ❤ Lightning can burn trees and cause forest fires.
(3) If you are at home during a tornado:
1)Go to a windowless interior room on lowest (2)level of your house. ...
(3)Get away from the windows.
1.
(a)A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
(b) In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure.
(2) The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations.
(3) When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound!
(2)
(a) Very strong winds may damage installations, dwellings, communication systems, trees., etc. resulting in loss of life and property. 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.
(b) If you are at home during a tornado:
(1)Go to a windowless interior room on lowest (2)level of your house. ...
(3)Get away from the windows.
(c) Stage 1: Warm moist air is forced upwards, forming a cumulus cloud. Stage 2: The warm air meets very cold air in the middle levels of the atmosphere. The two air masses collide, creating thunder and lightning. Stage 3: Eventually the warm moist air condenses as rain and the storm dies out.
