WEATHER

Atmospheric pressure is measured in

Milibars

The closer together the isobars are

The stronger the wind is

Front

Where two air masses meet

Occluded fronts when

A cold front takes over a warm front (cold occlusion) or vice versa (warm occlusion)

Occluded fronts bring

Changeable weather conditions

Cyclone/Depression

An area of low atmospheric pressure

They often

Pass over Ireland and bring wet/windy weather

Anticyclone

An area of high atmospheric pressure

They bring

Clear sunny weather

Hurricanes

Very large anticyclones

Temperature is measured using a

Thermometer (degrees Celsius)

Precipitation is measured using a

Rain gauge (milimetres)

Sunshine is measured using a

Campbell Stokes sunshine recorder (hours per day)

Wind speed is measured using an

Anemometer

Wind direction is measured using a

Wind vane

Wind strength is measured using the

Beaufort Scale

The Beaufort Scale describes

The effect the wind has on the landscape (12 forces)

Atmospheric pressure is measured using a

Barometer (milibars)

Humidity is measured using a

Hygrometer
