Westerlies Belt

• The Westerlies Belt is located between thirty and sixty degrees latitude.

• Prevailing winds in this region predominantly come from the west.

• Winds can travel across continents and dip into the Southern United States, bringing cold air.

• The mechanics of air movement can create systems of lifted air over cold fronts.

Anti-Emetic Cooling

• Describes the phenomenon where warm air moves in a westerly direction in the Westerlies Belt.

• As altitude increases, the atmospheric pressure decreases, leading to air expansion and cooling.

• Temperature cools at a fixed rate, approximately -6.5 degrees Celsius per kilometer of height.

Rain Patterns

• Rain is often represented using color coding, where intense rain is indicated in warmer colors.

• Low and high-pressure systems influence weather patterns, represented in millibars of barometric pressure.

• A typical high-pressure value can be around 1028 millibars, compared to a lower pressure system at around 982 millibars.

High and Low Pressure Systems

• Differences in barometric pressure indicate high or low-pressure systems, affecting storm patterns.

• The Bermuda High impacts weather by preventing some storms from reaching certain areas.

• Isobars represent areas of equal barometric pressure and can indicate the strength of high or low-pressure systems.

Frontal Storm Systems

• The presentation of warm and cold fronts influences rainfall distribution as storms move.

• Wind direction is affected by high and low-pressure systems and can be visualized with meteorological tools.

• Strong storms occur with significant pressure differences, with lower values indicating potential for hazardous weather.

Atmospheric Rivers

• Distinct from regular rainfall, atmospheric rivers can carry vast amounts of moisture.

• New intensity scales classify atmospheric rivers similar to hurricane categories, measuring moisture content in kilograms per meter per second.

• The behavior of air as it rises over mountains leads to cooling and condensation, which can lead to rainfall.

Measuring Atmospheric Conditions

• The pressure gradient signifies the difference between high and low-pressure areas, influencing storm development.

• Isobars on weather maps provide metrics for atmospheric pressure and system location.

Latent Heat Exchange

• Phase changes of water involve heat exchange, impacting temperature and moisture content.

• Water transitions from gas to liquid at approximately 100 degrees Celsius.

Summary of Atmospheric Dynamics

• Warm and moist air rises and cools, leading to the formation of weather systems.

• Meteorological warnings inform the public about potential hazards, based on atmospheric conditions.

• Weather forecasts may use polygons to indicate areas at risk for various weather events.
