Weather Balloon Radar temperature winds air pressure humidity precipitation Pressure Changes with Temperature Air flows in a clock-wise direction on the surface of the Earth. Warm, less dense air rises forming clouds Cold, dense air sinks to the surface of the Earth. Airs flows in a counter clockwise direction at the surface of the Earth. L Which Whatdirection will happen is the to warm the weather front moving? in Denton? 25°C 28°C 40°C 29°C 45°C High Pressure Low Pressure H L Warm Front Occluded Front Cold Front Stationary Front STATION MODEL is created when data that is collected is recorded on a map using a combination of symbols. Symbols for Fronts Isobars are lines that connect equal atmospheric pressure . The closer the isobars, the stronger the winds blow. The more spread out the isobars the gentler the winds. There are many areas of high and low pressure above the Earth’s surface due to uneven surface heating creating pressure gradients. Air moves from high pressure to low pressure forming winds. Cold, dense air sinks to the surface of the Earth forming. Warm, less dense air rises forming clouds Air flows in a clock-wise direction on the surface of the Earth. Cold, dense air sinks to the surface of the Earth. Warm, less dense air rises forming clouds Airs flows in a counter clockwise direction at the surface of the Earth. L Air flows in a clock-wise direction on the surface of the Earth in High Pressure areas. Airs flows in a counter clock-wise direction at the surface of the Earth in Low Pressure areas.
