a device like a wind mill to detect wind speed and direction

aerovane

2

an instrument used to determine wind speed

anemometer

3

is an instrument used to measure atmospheric pressure

barometer

4

is a weather phenomenon in which there is a descending movement of the air and a high pressure area over the part of the planet's

surface affected by it

anticyclone

5

the condition that exists when the wind distribution within a given region results in a net horizontal

inflow of air into the area

convergence

6

is an area of low atmospheric pressure characterized by inward spiraling winds

that rotate counter clockwise in the northern hemisphere

cyclone

7

the condition that exists when the wind distribution within a given region results in a net horizontal

outflow of air into the area

divergence

8

the curved airflow pattern around a pressure center resulting from a

balance among pressure gradient forces

gradient wind

9

areas have more atmospheric mass above their location

high pressure

10

a contour line of equal or constant pressure

isobar

11

areas that have less atmospheric mass above their location

low pressure

12

unit of pressure

millibar

13

a wind that conisistently blows from one direction

prevailing wind

14

a region of high atmospheric pressure

ridge

15

an elongated region of low atmospheric pressure

trough

16

is the flow of air or other gases that compose an atmosphere

wind

17

is a movable device attached to an elevated object such as a roof for showing the direction of the wind

wind vane

18

is a recording aneroid barometer

barograph

19

a type of barometer that consists of empty metal chambers

aneroid barometer

20

the force exerted by the weight of a column of air above a given point

air pressure

21

The force that generates wind is:

pressure gradient force.

22

An altimeter is an adaptation of the:

aneroid barometer.

23

Meteorologists convert all atmospheric pressure data to the

equivalent sea-level air pressure in order to:

remove the effects of elevation.

24

The addition of water vapor will cause the density of air to:

decrease.

25

A steep pressure gradient:

produces strong winds.

26

Upper air winds.

are generally faster than surface winds.

27

High air pressure zones are usually associated with:

relatively dry conditions.

28

If "fair" weather is approaching, the pressure tendency would

probably be:

rising.

29

When air moves from the ocean onto land.

converging winds and ascending air result over the land.

30

The Coriolis effect occurs because of this characteristic of the earth:

Its rotation
