Flashcards in Test #3 Deck (22):
1

At upper levels in the atmosphere, as a parcel of air moves in response to a pressure gradient, it is turned progressively to the right in the northern hemisphere until the pressure gradient and Coriolis forces balance to produce the:

geostrophic wind

2

The episodic cessation of the typical upwelling of cold deep water off the coast of Peru (warmer water in the eastern Pacific) and subsequent changes in weather patterns is called the ___________

El Nino

3

Lines of equal atmospheric pressure drawn on a weather map.

Isobars

4

Cloudy and rainy weather is often associated with the inward and upward convergence of air within ___________

Cyclone ("lows")

5

In the Hadley cell convection loop, air rises at the ITCZ and descends in the:

Subtropical high-pressure cells

6

Which areas of the United States experience tornadoes most frequently

Midwest (oklahoma, Kansas)

7

Sudden rise of water level caused by a hurricane

Storm surge

8

Heavy rains along narrow belt are typically found along _________ fronts associated with _________.

Cold; cyclones

9

Causes air to warm, producing clear conditions

anticyclones

10

Convergence and uplift typically cause condensation and precipitation

Cyclones

11

Physical state of the atmosphere at one location and at one time

Weather

12

Pressure exerted by the atmosphere because of the force of gravity acting on the overlying column of air

Atmospheric Pressure

13

Atmospheric pressure ___________ with altitude.

decreases

14

An effect of the Earth's rotation that acts like a force to deflect a moving object on the Earth's surface

Coriolis Effect (CE)

15

Wind at high levels (upper levels) above the Earth's surface moving parallel to the isobars, at a right angle to the pressure gradient

Geostrophic Wind

16

A low-latitude atmospheric circulation cell with rising air over the equatorial trough and sinking air over the subtropical high-pressure belts.

Hadley Cell

17

Response to differences in pressure

Wind

18

Rising air is associated with

cyclones

19

Descending air is associated with

anticyclones

20

Patterns of atmospheric circulation that lead to distinctive weather events, such as cyclones or thunderstorms

Weather systems

21

An extensive body of air in which temperature and moisture characteristics are fairly uniform over a large area

Air masses

22

Identifies a zone of transition between air of different properties
