Pilotenausbildung: Meteorology

An aircraft is approaching under visual flight rules an airfield whose runway is parallel to the coast. When downwind over the sea, the airfield is on the left. What wind effect should be anticipated on final approach and landing during a sunny afternoon

When otherwise calm and clear conditions exist a station on the shore of a large body of water will experience wind

The greater the pressure gradient the

When isobars, for an area in the mid-latitudes on a weather map, are close together, the wind is most likely to be

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

In the northern hemisphere the wind at the surface blows

Wind is caused by

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

The Foehn wind is a

The sea breeze is a wind from the sea

Low level vertical wind shear can be expected during the night

In an area of converging air

You are flying from east to west in the northern hemisphere at the 500 hPa pressure surface. Which of the following statements is correct?

Geostrophic wind is the wind when isobars are

Fair weather cumulus often is an indication of

What relationship exists between the wind at 3000 feet and the surface wind?

The wind tends to follow the contour lines (isohypses) above the friction layer because

The wind speed in a system with curved isobars compared to a system with straight isobars is (other conditions being the same)

Divergence in the upper air results, near the surface, in

The geostrophic wind depends on

In a mountain-valley wind circulation, the mountain wind blows

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

The difference between geostrophic wind and gradient wind is caused by

The vertical extent of the friction layer depends primarily on

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

The Chinook is a

The geostrophic wind speed is directly proportional to the

A strong, dry and warm katabatic wind, produced by prior enforced ascent of air over hills or mountains is known as a

Geostrophic wind

In a low pressure system the convergence at the surface is caused by

What is the name of the northerly, cold and strong wind, that sometimes blows over a certain part of Europe?

What are the characteristics of the Bora ?

What is the name of the hot, local wind, that blows downwards from mountain chains? In the Alps, for instance, it may exist both as a southerly or northerly wind depending on the weather situation.

Which one of the following local winds is a Foehn wind?

The Bora is a

For a similar pressure gradient, the geostrophic wind speed will be

For the same pressure gradient at 60°N, 50°N and 40°N the speed of the geostrophic wind will be

Under anticyclone conditions in the northern hemisphere, with curved isobars the speed of the gradient wind is

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

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
