Do you know about cyclones, formation, types and effects? Let us solve a quiz based on cyclones that will enhance knowledge and also help in the preparation of several competitive examinations.
Amphan cyclone on 20 May, 2020, will likely to move north-northeastwards across the northwest Bay of Bengal and cross Hatiya Islands (Bangladesh) close to Sundarbans as a very severe Cyclonic Storm with maximum sustained wind speed of 155-165 kmph gusting to 180 kmph as per IMD.
1. Which of the following statement is/are true for cyclones?
A. Cyclones are centres of low pressure surrounded by closed isobars and having increasing pressure outwards.
B. Cyclones range in shape from circulars, elliptical to 'V' shaped.
C. Cyclones have an immense influence on the climate and weather.
D. All the above are correct.
Ans. D
Explanation: Cyclones are centres of low pressure surrounded by closed isobars and having increasing pressure outwards. From the outside, it has closed air circulation towards the Central low pressure in such a way that air blow inward in anticlockwise in the North Hemisphere and clockwise in the South Hemisphere. They range in shape from circulars, elliptical to 'V' shaped. They have an immense influence on the climate and weather.
