Synoptic Chart Time The weather is made by the heating and cooling of the air, land and water. This makes pressure differences across the planet A synoptic chart is a map of pressure difference and weather systems. Mariners read this map to forecast the weather High Pressure System Low Pressure System H 1032 hPa L 983 hPa Pressure is measured in hectopascals hPa Heavy air presses down The movement of air from high to low pressure makes wind Wind Low Pressure Wind Low Pressure High Pressure High Pressure High Pressure System Wind Rotates Anticlockwise Low Pressure Low Pressure System Wind Rotates Clockwise Lines of equal pressure a called isobars. Pressure is the same along an isobar. Isobars Winds travel in the direction of isobars Isobars far apart Lighter winds Wind speed and direction Isobars close together Strong winds Monsoon Trough Trough Cold Front Cold Front Wind, Rain, Storms Warm Front Drizzle Trough Unsettled, Storms Monsoon Trough Wet Season Storms Warm Front
