Air pressure goes nowhere
Air pressure always flows from areas of low pressure to areas of high pressure
Air pressure always flows from areas of high pressure to areas of low pressure
Air Pressure is too fat to go anywhere.
The Coriolis Effect
The Trade Winds
The Walker Circulation
The winds go outwards and backwards in both high and low pressure systems.
The winds go inwards and upwards in a low pressure system
The winds always go the same way.
The winds go downwards and outwards in a high pressure system
The winds go downwards and outwards in a low pressure system.
Towards the Equator
They never go above 1013 hpa.
They are generally associated with very hot weather
They generally stay in the 900 hpa area.
Air near the centre of a low pressure system is unstable
Associated with unsettled weather, cloudy conditions, wind, cyclones and periods of rain.
High pressure systems
Low pressure systems
Show lines of equal air pressure
Are measured in hectopascals
Are not on weather maps
Are measured by an anenometer
The closer the lines, the stronger the wind
Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.
A and d
A, d and e
A stream of negative charges pours down towards a high point where positive charges have clustered
A bolt of lightning heats the air along its path causing it to expand rapidly.

Tropical cyclones are intense low pressure systems
Tropical Cyclones do not exist in Australia
Tropical Cyclones are mythical
They rotate clockwise in the Southern Hemisphere and counter-clockwise in the Northern Hemisphere
They form over tropical oceans that must be at a temperature of 24-26 degrees
Floods or storm surges

The funnel of a tornado is called a vortex. When it drops down, it hisses
The funnel of a tornado is called a vortex. When it drops down, disappears
The funnel of a tornado is called an eye. When it drops down, it hisses
The funnel of a tornado is called a eye. When it drops down, it disappears
