Verified Answer
With reference to the Trade Winds, consider the following statements:1...
- Trade winds: It is the wind blowing steadily towards the equator from the north-east in the northern hemisphere or the south-east in the southern hemisphere, especially at sea. Two belts of trade winds encircle the earth. These winds are called trade winds because of the fact that they helped the sea merchants in sailing their ships as their (of trade winds) direction remain more or less constant and regular. There is more or less regular inflow of winds from subtropical high-pressure belts to the equatorial low-pressure belt. Hence statement 2 is correct.
- According to Ferrefs law (based on Coriolis force generated by the rotation of the earth), trade winds are deflected to the right in the northern hemisphere and to the left in the southern hemisphere. Hence statement 3 is correct.
- There is much variation in the weather condition in different parts of the trade winds. The poleward side of the trade winds or eastern sides of the subtropical anticyclones are dry because of the strong subsidence of air current from above.
- Because of the dominance of the anticyclonic conditions, there is strong atmospheric stability, strong inversion of temperature and clear sky.
- On the other hand, the equatorward part of the trade winds are humid because they are characterized by atmospheric instability and much precipitation as the trade winds while blowing over the oceans pick up moisture.
- Trade winds are more regular and constant over the oceans than over the lands. At some places on the lands (eg. S.E. Asia and the southern USA) the trade winds disappear during the summer season due to the formation of low-pressure cells because of high temperature but the trade winds are more constant and regular over the continents during the winter season. Hence statement 1 is not correct
- It may be pointed out that the zone of trade winds is called Hadley Cell on the basis of the convective model prepared by Hadley for the entire earth.
Most Upvoted Answer
With reference to the Trade Winds, consider the following statements:1...
The Trade Winds are a persistent pattern of easterly surface winds found in the tropics. They are caused by the rotation of the Earth and the differences in solar heating between the equator and the poles.
Correct statements about the Trade Winds are:
2. They blow from the subtropical high-pressure belt to the equatorial low-pressure belt. This is because air moves from areas of high pressure to areas of low pressure, and the Trade Winds are part of the global circulation of air that helps to transport heat and moisture around the planet.
3. They are deflected to the right in the northern hemisphere and to the left in the southern hemisphere. This is due to the Coriolis effect, which causes objects (including air masses) moving on the surface of the rotating Earth to appear to curve to the right in the northern hemisphere and to the left in the southern hemisphere.
Statement 1 is incorrect. The Trade Winds are actually more constant in the winter season than in the summer season over land, because the difference in temperature between the land and the ocean is greater in winter than in summer, and this affects the strength and direction of the winds.
Therefore, the correct answer is option B (2 and 3 only).
