Mistral

The mistral is a strong, cold, northwesterly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. It produces sustained winds often exceeding 66 km/h (41 mph), sometimes reaching 185 km/h (115 mph). It is most common in the winter and spring, and strongest in the transition between the two seasons. Periods of the wind exceeding 30 km/h (19 mph) for more than sixty-five hours have been reported.

A Correct answer
Explanation

Pampero 
The pampero is a burst of cold polar air from the west, southwest or south on the pampas in the south of Brazil, Argentina, Uruguay, Paraguay, and Bolivia. This wind (often violently) picks up during the passage of a cold front of an active low passing by. It takes the form of a squall line and there is a marked drop in temperature after its passing. The Pampero is most common in winter in the southern hemisphere (principally between May and August). During the summers in the region around Buenos Aires, the pampero storms are a welcome feature marking the end of long periods of high humidity and extreme heat.

D Correct answer
Explanation

Very small area,

The local winds moderates the climate of nearby areas with sudden increase or decrease in the temperature and humidity. In valleys of the mountains, two kinds of winds are particularly active - anabatic winds and katabatic winds.  These winds are result of differential heating of the land and the sea.

B Correct answer
Explanation

The instrument which used to measure wind direction is called wind vane. It is generally located at the highest point of a building. This is pointed at the direction in which the wind is blowing. Wind vane is used to predict the weather of a particular place, as the direction of wind plays important role in determining weather of a place.

Wind forms as a result of difference in _______.

  1. humidity

  2. pressure

  3. temperature

  4. altitude
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wind is been defined as air in horizontal motion caused by difference in pressure. There are two type of movement in the atmosphere : horizontal movement and vertical movement. Vertically moving air columns are known as currents. Winds are the means by which uneven distribution of pressure over the globe is balanced out .
