Weather Hazards And Climate Change

Front 1

Air masses

Back 1

Large areas of either warn or cold air. When they meet they cause rain.

Front 2

Annual Temperature Range

Back 2

The difference between the highest and lowest temperatures of a place in a year.

Front 3

Arctic Maritime

Back 3

Cold and moist air mass from the north bringing very cold and damp weather, often snow in winter.

Front 4

Arid

Back 4

An area with littler or no regular rainfall.

Front 5

Atmosphere

Back 5

The gases that surround the earth.

Front 6

Axial tilt

Back 6

Over 40,000 years the angle of the tilt changes, a greater angle of tilt is associated with higher summer temperatures but cooler winters.

Front 7

CERF

Back 7

The United Nations' Central emergency response fund.

Front 8

Circulation cells

Back 8

Transfer surplus heat energy rim the equator to the poles.

Front 9

Climate

Back 9

The average temperature and precipitation figures for an area.

Front 10

Climate change

Back 10

A long term movement in weather and climate patterns and average temperatures across the earth.

Front 11

Climate cycles

Back 11

Long term changes in climate around earth caused by different factors which can lead to glacial and interglacial periods

Front 12

Climate graph

Back 12

Graph that shows temperature as a line at the top and rainfall in bars beneath on the same graph.

Front 13

Coriolis force

Back 13

The deflection of air movement caused by the spinning of earth. Creates the spinning wind pattern around low pressure systems.

Front 14

Crop yields

Back 14

The amount of crops and food produced, majorly impacted by changes in climate (rain and sun levels)

Front 15

Cyclone

Back 15

A low pressure weather system characterised by inward spiralling winds also known as a hurricane or typhoon

Front 16

Dendrochronology

Back 16

Using tree rings to record changes in short to medium term changes in climate.

Front 17

Depression

Back 17

A low pressure system that produces clouds wind and rain.

Front 18

Drought

Back 18

A period of below average precipitation resulting in prolonged shortages in waters supply.

Front 19

Eccentricity

Back 19

Over 100,000 years there are changes in the shape of the earth's orbit, more circular for warmer (interglacial periods) and more elliptical for cooler (glacial periods).

Front 20

El Nino

Back 20

A cyclical change in sea temperature patterns in the Pacific Ocean which can have major impacts on weather and climate in the Americans and East Asia and Australasia.
