1145 - What do high and low pressure symbols, fronts, and typhoons on weather maps represent

High and Low Pressure Symbols: These symbols on a weather map show areas of different air pressures. - High Pressure (H): Air is sinking, and the weather is usually clear and sunny. - Low Pressure (L): Air is rising, and the weather is usually cloudy and rainy.

Fronts: Fronts are areas where two different air masses meet. They can bring changes in the weather. - Cold Front: A line with triangles pointing towards you. This means cold air is moving into the area. - Warm Front: A line with half-circles pointing away from you. This means warm air is moving into the area.

Typhoons: Typhoons are strong storms with high winds and heavy rain. They are similar to hurricanes, but they happen in different parts of the world.

On a weather map, you might see: - A spiral symbol for a typhoon, showing its wind direction and strength. - Arrows showing the direction the typhoon is moving. - A circle or colors around the typhoon, showing the area that will be affected by the storm.
