In the International Standard Atmosphere the decrease in temperature with height below 11 km is

Which statement is correct regarding the International Standard Atmosphere ?

With which type of cloud are tornadoes normally associated ?

A 200 hPa pressure altitude level can vary in height. In temperate regions which of the following average heights is applicable ?

Friction between the air

You are flying at 2 500 FT/AGL, with a southerly wind, and intend to land at an airport, at sea level directly below. From approximately which direction would you expect the surface wind (mid-latitude, northern hemisphere)?

At what time of the year

At the approach of a warm front (northern hemisphere) the wind direction changes from the surface up to the tropopause. The effect of this change is that the wind

During periods of prolonged clear skies associated with anticyclonic conditions, the

During a descent from 2000 FT above the surface to the surface (no frontal passage) the wind normally

In the northern hemisphere the wind at the surface blows

What relationship exists between the wind at 3000 feet and the surface wind? is across the isobars toward the low pressure and the surface wind is weaker.

The vertical extent of the friction layer depends primarily on

In the northern hemisphere a pilot flying at 1000 FT/AGL directly towards the centre of a low pressure area, will find the wind blowing from

If you are flying at FL 300 in an air mass that is 15° C warmer than a standard atmosphere, what is the outside temperature likely to be?

If you are flying at FL 120 and the outside temperature is -2° C, at what altitude will the "freezing level" be?

In the northern hemisphere the gradient wind of a cyclonic pressure distribution is 350/24, over the sea the surface wind would approximate

If you are flying at FL 100 in an air mass that is 10° C warmer than a standard atmosphere, what is the outside temperature likely to be?

In the northern hemisphere with an anticyclonic pressure system the geostrophic wind at 2000 FT over the sea is 060/15. At the same position the surface wind is most likely to be
