[#161] Consider the following statements: 1. Either of the two belts over the oceans at about 30° to 35° N and S Latitudes is known as Horse Latitude. 2. Horse latitudes are low pressure belts. Which of the statements given above is/are correct?
Correct Answer
(A) 1 only
Explanation
Solution: Either of the two belts over the oceans at about 30° to 35° N and S latitudes is known as Horse Latitude. Horse latitude, either of two subtropical atmospheric high-pressure belts that encircle Earth around latitudes 30°– 35° N and 30°– 35° S and that generate light winds and clear skies. Because they contain dry subsiding air, they produce arid climates in the areas below them.
[#162] Warm dry winds blowing down the east slopes of Rockies are known as ________
Correct Answer
(D) Chinook
Explanation
Solution: Warm dry winds blowing down the east slopes of rockies is known as chinook. They are a type of warm, dry wind that occur on the downward slope of a mountain when warm air has lost its moisture.
[#163] The study of the processes of atmosphere is called as
Correct Answer
(B) Meteorology
Explanation
Solution: It is the branch of science which is concerned with the processes of atmosphere e.g. forecasting weather. Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting.
[#164] Consider the following statements 1. Tropical cyclones have circular isobars. 2. Tropical cyclones originate entirely within the tropical air mass. 3. The intensity and magnitude of hurricanes generally exceed those of typhoons. 4. Tropical cyclones are more destructive than the western disturbances. Select the correct answer by using the following codes
Correct Answer
(A) 1, 2 and 4
Explanation
Solution: Tropical cyclones have circular isobars. A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones originate entirely within the tropical air mass. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Tropical cyclones are more destructive than the western disturbances. Tropical cyclones out at sea cause large waves, heavy rain, flood and high winds, disrupting international shipping and, at times, causing shipwrecks.
[#165] Which of the following is a cold wind?
Correct Answer

Explanation
Solution: Extremely cold northeasterly or easterly winds blowing in eastern Russia and central Siberia are called buran.
