Atmosphere MCQ Question and Answer | Geography MCQ Question

In the northern hemisphere, isotherms bend sharply equator-ward over the continents during winter. Large landmasses in the Northern hemisphere cause isotherms to bend toward the equator in winter and poles in summer as they change their temperature much more than the water.

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.

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.

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.

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.

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

The albedo of Cirrus cloud is the highest. Cirrus are thin, wispy clouds that appear at high altitude and consist of ice crystals.

Since, the insolation is highest at equator; temperature should be highest at the equator and lowest near the poles, however actually it is not. Highest temperature on earth is recorded at a few degrees north of equator. Altitude is the second major control of temperature of a place. The temperature depends upon albedo of the surface also.

Land masses are heated and cooled much faster than water bodies. Land gets heated by conduction, Water has higher specific heat and Water gets heated by convection.

The correct sequence of the zonal pressure belts are Equatorial low, Subtropical high, Subpolar low and Polar high.
