Troposphere,

Local winds occur on a small spatial scale, their horizontal dimensions typically several tens to a few hundreds of kilometres. They also tend to be short-lived lasting typically several hours to a day. There are many such winds around the world, some of them are cold, some warm, some wet, some dry. There are many hazards associated with the winds.

The main types of local winds are:

C Correct answer
Explanation

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.

Reveal answer Fill a bubble to check yourself
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.

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.
