Answer

A straight jet stream near a low pressure area

Answer

A westerly jet stream at low latitudes in the summer

Answer

A jet stream, with great spacing between the isotherms

Question 4

Accepted Answer

Surface wind speed tends to be highest during the mid afternoon

Answer

Surface wind speed tends to be highest at night

Answer

Angle between isobars and surface wind direction tends to be greatest in the mid afternoon

Answer

Wind tends to back from early morning until early afternoon

Question 5

Accepted Answer

From the ground up to a maximum of FL 450.

Answer

From the ground up to about FL 200.

Answer

From the ground up to about FL 100.

Answer

From the base of the clouds up to about FL 200.

Question 6

Convective weather phenomena include:

Accepted Answer

Thunderstorms, hail, tornadoes, wind gusts, heavy showers, lightning strikes.

Answer

Heavy showers, lightning strikes, hail, mist, squalls, light rain over a large area.

Answer

Thunderstorms, tornadoes, hail, haze, wind gusts, advection fog.

Answer

Hail, lightning strikes, wind lulls, squalls, stratocumulus, low level wind maximum.

Question 7

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

Accepted Answer

Frictional forces

Answer

Centripetal forces

Answer

The inbalance of the horizontal gradient force and the Coriolis force

Answer

The curvature of the isobars

Question 8

What characterizes a stationary front ?

Accepted Answer

The surface wind usually has its direction parallel to the front

Answer

The weather conditions that it originates is a combination between those of an intense cold front and those of a warm and very active front

Answer

The warm air moves at approximately half the speed of the cold air

Answer

The surface wind usually has its direction perpendicular to the front

Question 9

Extensive cloud and precipitation is often associated with a non frontal thermal depression because of:

Accepted Answer

Surface convergence and upper level divergence causing widespread ascent of air in the depression

Answer

Surface divergence and upper level convergence causing widespread ascent of air in the depression

Answer

Surface divergence and upper level convergence causing widespread descent of air in the depression

Answer

Surface convergence and upper level divergence causing widespread descent of air in the depression
