Questions weather

Question 1

Ambient lapse rate

Answer 1

rate of decrease in temperature with altitude. Stability can be determined

Question 2

unstable cold airmass moving to warm area.

Answer 2

Cumuliform clouds, turbulence and good visibility

Question 3

Unstable air means

Answer 3

Cumuliform clouds,
showery precipitation,
turbulnace,
good visibility

Question 4

Lenticular altocumulus clouds

Answer 4

created by on the crest of waves created by the barrier in the wind flow.
very Strong turbulence

Question 5

Jet stream

Answer 5

high altitude, may be marked by cirri form clouds

Question 6

Small or huge temp. change in stratosphere (above the stratosphere)

Answer 6

small

Question 7

Form of advection fog

example

Answer 7

Moist air moves over colder ground to water

for example: an air mass moving inland from the coast in winter

Question 8

Temperature inversion

Answer 8

is standard lapse rate and stable air

Question 9

Wind necessary for which type of fog

Answer 9

advection and upslope

Question 10

Why at 5000 ft wind is from southwest but surface is from south

Answer 10

Coriolis force deflected by surface friction

Question 11

4 families of clouds

Answer 11

High, Middle , Low and extensive vertical development

Question 12

cumulus clouds indicate

Answer 12

good visibility, turbulence at and below level clouds

Question 13

feature associated to tropopause

Answer 13

abrupt change in lapse rate and hight is 20000 to 65000

Question 14

Wind speed of jet stream

Answer 14

50 knots

Question 15

unstable airmass is forced to ascend a mountain slope

Answer 15

clouds with extensive vertical development

Question 16

flying and encountered wet snow, it means

Answer 16

temperature is above freezing, sublimation is happening, and snow is melting

Question 17

warm rain fall though cool air near the surface and fog happens in

Answer 17

cold frontal

Question 18

Average hight of the troposphere in the middle latitude

Answer 18

37000

Question 19

The layers of of atmosphere from the earth’s surface

Answer 19

troposphere, stratosfere, mesosphere

Question 20

frontal system and clouds, pressure and wind

Answer 20

Clouds: make gradual or abrupt
Clouds: not all frontal systems
Wind: change in direction, speed

Question 21

inversion

Answer 21

Increase in temperature with altitude

often happens near the ground on clear cool night with light wind

Question 22

Cumulonimbus vs towering cumulus. Which one has the greatest turbulence

Answer 22

cumulonimbus

Question 23

Lentocular clouds in mountainous areas means

Answer 23

turbulence

Question 24

frontal waves normally form on

Answer 24

slow moving cold fronts or stationary fronts.

Question 25

Convective turbulence almost always present

Answer 25

During warm summer afternoon when winds are light

Question 26

temperature inversion Why and expect?

Answer 26

increase temperature with altitude clear night and wind is light lowest few thousands feet above the ground. wind shears will be seen and generates turbulence

Question 27

Dry Adiabatic lapse rate is

Answer 27

3 Celsius every 1000ft

Question 28

Radiation fog

Answer 28

Warm, moist air over low flatland areas on calm nights

Question 29

weather conditions when there is a low level temp. inversion

Answer 29

smooth air, low visibility due to haze, fog, low clouds

Question 30

Growth rate of precipitation

Answer 30

upward currents

Question 31

strength and location of jet stream

Answer 31

strong in winter and shifts farther south un winter. | weaker in north in the summer time

Question 32

Clouds, fog and dew always will form

Answer 32

water vapor condenses
