High Pressure
An area on Earth’s surface where the atmospheric pressure is higher than the surrounding areas, causing air to sink and generally leading to clear skies and calm weather conditions
Low Pressure
An area where the atmospheric pressure is lower than the surrounding areas, causing air to rise and often leading to cloudy and stormy weather conditions
Temperature

Wind Speed
Speed of weather related air movement
