Question

please help me with this question.

The rotation of the earth on its axis helps develop major surface winds, known as prevailing winds, which dissipate the sun's uneven heating by moving heated air masses from the equator to cooler areas in the north and south. 60° N 30° N These winds, which move in _differing directions, affect climate by continually distributing heat and moisture over the earth's surface. Referring to the adjacent illustration, the winds labeled D and prevailing winds known as 30° S represent the 60° westerlies trade winds POLAR CAP Earth's rotation and prevailing winds also drive the directions of major ocean currents on the planet. Because water can hold and release a great deal of heat, these currents play an important role in determining regional climate and vegetation, particularly for regions adjacent to the ocean. Like prevailing winds, ocean currents help redistribute heat over the surface of the earth. 60° N 30° N For example, New York City in the United States and Lisbon in Portugal are roughly the same distance from the equator. Judging by ocean currents alone, which of these two cities would you expect to be warmer? 30° S 60° O Lisbon O New York City

Explanation / Answer

1. The winds labeled D represent the prevailing winds known as WESTERLIES. Basically if the winds move from West to East, they are called westerlies and the direction of the westerlies are exactly opposite to the direction of trade winds. Westerlies are also termed as ANTITRADE WINDS.

2. Answer: LISBON

Explanation: Lisbon experiences warmer temperatures compared to New City. Even though both are nearly located at the same latitude, basically Lisbon has long hot summers and the months during summer are very hot with temperatures reaching 35°C. Where as New York have variety of weather conditions and temperatures. It's highest temperatures during the month of July ranges about 28°C. So clearly even both Lisbon and New York have the same distance from the equator, Lisbon would expect to be warmer.
