Weather is simple what the air or atmosphere is like that at that time. No matter what the air is – cold, cool, warm, hot, calm, breezy, windy, dry, moist, or wet – that is still weather.
Air pressure differs across all parts of the Earth’s surface and this difference causes winds. Air will move from an area of high pressure, or an anticyclone to an area of low pressure or a depression.
Depression are usually associated with bad weather conditions and rain. These changes in air pressure can be measured by an instrument call barometer.
When meteorologists talk about a weather front, they are referring to the boundary between two masses of air at different temperatures and pressures. Increasingly accurate forecasting is now possible with aid of satellites and computer technology.
