Climate is the average weather conditions that occur in a region over a long period of time.
The amount of force pushing on you due to the weight of the air.
High and Low Pressure Systems
When the air is compressed it is under “high pressure”.
Weather forecasters measure air pressure with a Barometer.
Standard Atmospheric Pressure is 101.325 kPa
Air pressure can tell us about what kind of weather to expect as well.
If a high pressure system is on its way, you can expect cooler temperatures and clear skies.
If a low pressure system is coming, then look for warmer weather, storms and rain.
Wind is air that is moving from a high pressure system to a low pressure system.
The spinning of the Earth also creates wind (The Coriolis Effect). This causes the prevailing westerly winds in North America.
Most clouds are associated with weather.
They are divided into groups based on the height of the cloud’s base about the Earth’s surface.
