Atmosphere & Winds

Question 1

What is the height of troposphere?

Answer 1

36,000 feet

Question 2

What atmosphere can be found above the troposphere?

Answer 2

Stratosphere, mesosphere, and thermosphere

Question 3

What is convection?

Answer 3

-Cooler tends to sink and replace warm air. This circulation process is known as convection

Question 4

What are lines connecting points of equal pressure called

Answer 4

Isobars

Question 5

What is ridge

Answer 5

Area of high pressure

Question 6

What is trough & Col

Answer 6

Trough is region of low pressured Col is region of neutral between trough & ridge

Question 7

How are winds formed?

Answer 7

Winds are formed by a mixture of pressure gradient, and Coriolis force, Corliss force defects winds towards the right in the northern hemisphere

Question 8

What is sea breeze?

Answer 8

In the day, the warm air over the land starts rising up, so the cool air over the sea starts to flow towards the land, thus causing sea breeze

Question 9

What is Valley breeze and how fast is it?

Answer 9

. During the day, the top of mountains are heated because of the sun and the warm air rises up and the cool air from the valley starts to replace it the creating a breeze from the valley towards the mountains top they can be between 5 to 20 knots

Question 10

What are mountain breeze, and how fast are they?

Answer 10

At night, the higher peaks cool off easily , thus it starts to replace the warmer air over the valleys, thus forming a down flow called mountain breeze, they can be 5 to 15 kn

Question 11

What are katabatic winds?

Answer 11

Any down slope, winds that are stronger than mountain base are called katabatic

Question 12

What are cold down, slope winds?

Answer 12

When large ice and snow fields accumulate on top of mountains because they are so heavy, they are forced down the mountain and thus develop into down slope winds

Question 13

What is atmospheric stability?

Answer 13

It is the atmosphere is resistance to vertical motion

Question 14

What is lapse rate?

Answer 14

The rate at which temperature decreases within increase in altitude is referred to as lapse

Question 15

What is dry at adiabatic lapse rate?

Answer 15

3° per 1000 feet

Question 16

What is the temperature, inversion, and what kind of weather can be found?

Answer 16

A temperature inversion is when an increase in altitude increases temperature below the inversion visibility of restricted by fog, haze smoke and low clouds

Question 17

What is humidity and relative humidity?

Answer 17

Humidity simply refers to the moisture in the air and relative humidity is the actual amount of moisture in the air compare to the total amount that could be present

Question 18

What is dewpoint?

Answer 18

Dewpoint is the temperature at which a particular mass of air is said to be saturated
