Meteorology Test 3

Front 1

In warm clouds up to 1 km how to rain droplets grow?

Back 1

Collision and coalescence.

Front 2

Does condensation provide an efficient means of raindrop formation?

Back 2

No

Front 3

In warm clouds how to rain droplets form through collision?

Back 3

Small cloud droplets join together by random collisions.

Front 4

In warm clouds how do rain droplets form through coalescence?

Back 4

Large and faster moving cloud droplets over take smaller and slower droplets in their path to form larger droplets.

Front 5

True or false. Large rain droplets occur due to liquid water content, range of cloud droplet sizes, cloud thickness, updraft strength, and droplets electrical charges.

Back 5

True.

Front 6

True or false. In cold clouds above 6-7 km rain droplets form through accretion and aggregation.

Back 6

True

Front 7

In high, cold clouds how do rain droplets form through accretion?

Back 7

A process where ice Crystal growth occurs by sweeping up supercooled water drops.

Front 8

In high, cold clouds how do rain droplets form through aggregation?

Back 8

The process by which ice Crystal collide and form a single larger ice particle.

Front 9

In the northern hemisphere how do winds blow around a low pressure center?

Back 9

Counterclockwise and towards the low pressure.

Front 10

In the northern hemisphere how do winds blow around a high pressure center?

Back 10

Clockwise and away from the high pressure.

Front 11

What are the four forces that influence winds?

Back 11

Pressure gradient Force, coriolis Force, centrifugal force, frictional force

Front 12

Does pressure increase or decrease with increased height?

Back 12

Decreases.

Front 13

Does cold air shrink or expand?

Back 13

Shrink

Front 14

Does warm air shrink or expand?

Back 14

Expand

Front 15

Does air move from high to low pressure or low to high pressure?

Back 15

High to low pressure.

Front 16

What is the pressure gradient Force?

Back 16

Horizontal difference in atmospheric pressure that causes wind to blow.

Front 17

True or false. Steep pressure gradient correspond to stronger pressure gradient force and vice versa.

Back 17

True

Front 18

What is the Coriolis effect?

Back 18

Apparent force due to the rotation of the Earth

Front 19

The magnitude of the Coriolis effect depends on what two factors?

Back 19

Latitude and speed of air.

Front 20

True or false. The lower the latitude the larger the Coriolis effect?

Back 20

False

Front 21

The faster air moves what happens to the Coriolis Force?

Back 21

It becomes larger

Front 22

Due to the Coriolis effect what happens to the intended path have a parcel in the northern hemisphere?

Back 22

Moves to the right of its intended path

Front 23

What does the Coriolis Force have an influence on? Wind direction or wind speed?

Back 23

Wind direction.

Front 24

Frictional force depends on what two factors?

Back 24

Speed of the air parcel and the roughness of the Earth's surface.

Front 25

If wind speed and/or friction increase what happens to frictional force?

Back 25

Frictional force increases.

Front 26

When is frictional force important?

Back 26

In the friction layer the lowest thousand meters of the atmosphere.

Front 27

What is buys ballets law?

Back 27

With wind at your back low pressure will be to your left and high-pressure to your right

Front 28

In scales of motion what is microscale?

Back 28

Up to 1 km.

Front 29

In scales of motion what is mesoscale?

Back 29

1 km to 200 km

Front 30

In scales of motion what is synoptic scale?

Back 30

200 km to 2000 km

Front 31

And scales of motion what is planetary scale?

Back 31

Anything over 2,000 km
