Question 2

Fog produced by frontal activity is a result of saturation due

Answer 2

evaporation of precipitation

Hazardous windshear is commonly encountered

Answer 3

in areas of temperature inversion and near thunderstorms.

Question 4

low•l evel wind shear may occur when

Answer 4

there is a low•level temperature inversion with strong winds above the inversion

Question 5

If a temperature inversion is encountered immediately after takeoff or during an approach to a
landing ,a potential hazardous exists due to

Answer 5

wind shear

Question 6

Convective currents are most active on warm summer afternoons wheo winds are

Answer 6

light

Question 7

What is indicated if ice pellets are encountered at 8,000 feet?

Answer 7

Freezing rain at higher altitude.

Question 8

If clouds form as a result of very stable, moist air being forced to ascend a mountain slope, the
clouds will be

Answer 8

stratus type with little vertical development and little or no turbulence.

Question 9

Changes in atmospheric stability are inversely related to what?

Answer 9

1) Temperature
(density) changes with height
2) If temperature lapse rates increase, then stability decreases.

Question 10

Which would increase the stability of an air mass?

Answer 10

Cooling from below.

Question 11

clouds types which include convective turbulence?

Answer 11

Towering cumulus clouds

Question 12

hazardous weather that created by Cumulonimbus clouds are?

lightning, hail, tornadoes, gusty winds, and wind shear.

Question 13

standing lenticular altocumulus clouds is a good indication of

Answer 13

very strong turbulence

Question 14

How Standing lenticular altocumulus clouds are formed?

Answer 14

crests of waves created by barriers in the wind flow.

Question 15

The formation of either predominantly strati form or predominantly cumuliform clouds is
dependent upon the

stability of the air being lifted

Question 16

Which are characteristics of a cold air mass moving over a warm surface?

Answer 16

Cumuliform clouds, turbulence, and good visibility

Question 17

Fog produced by frontal activity is a result of saturation due to

Answer 17

evaporation of precipitation

Question 18

Features of Frontal fog

Answer 18

can become quite dense and 1) continue for an extended period of time.
2) extend over large areas,
3) is most commonly associated with
warm fronts, but can occur with other fronts as well.

Question 19

What is an important characteristic of wind shear?

Answer 19

II can be present at any level and can exist in both a horizontal and vertical direction.

Question 20

Why, low-level wind shear is especially hazardous

Answer 20

due to the proximity of an

aircraft to the ground.(greater than 25 knots).

Question 21

What is Wind Shear?

Answer 21

a sudden, drastic change in wind speed and/or direction over a very small area.

Question 22

Low-level wind shear is commonly associated with

Question 23

Hazardous windshear is commonly encountered

Answer 23

in areas of temperature inversion and near thunderstorms

Question 24

low level wind shear may occur when

Answer 24

there is a low level temperature inversion with strong winds above the inversion.

Question 25

If a temperature inversion is encountered immediately after takeoff or during an approach to a
landing ,a potential hazard exists due to

Answer 25

wind shear.

Question 26

Convective currents are most active on warm summer afternoons when winds are

Answer 26

light

Question 27

What is Convective turbulence is

Answer 27

turbulent vertical motions that result from convective currents and the subsequent rising and
