INDIAN GEOGRAPHY

Detailed explanation-1: -The winter westerlies, often from the southwest, bring in warm tropical air; in summer, by contrast, they veer to the northwest and bring in cooler Arctic or subarctic air. In Mediterranean Europe the rain-bearing westerlies chiefly affect the western areas, but only in winter.

Detailed explanation-2: -When it is negative and pressures are higher over the poles, the flow is more meridional, blowing from the direction of the pole towards the Equator, which brings cold air into the mid-latitudes.

Detailed explanation-3: -Are the westerlies warm or cold? The westerlies are both warm and cold. The westerlies in the winter often come from the southwest and bring in the warm breeze. In summer, they flow from the northwest and bring in the much cooler breeze from the arctic.

Detailed explanation-4: -Traveling cyclones and anticyclones are characteristic of the westerlies because the westerlies are baroclinic. This baroclinic structure assures that wind speeds will increase with height up to the tropopause where the atmosphere becomes isothermal or inverted.
