Weather is the state of the atmosphere at a particular place and time. The amount of water in the air, the temperature of the air and the precipitation are all used to describe the atmosphere.
Humidity is the amount of water in the air. Summer Days Hygrometer So how does water in the air affect the weather? Clouds Precipitation Water in the Air
So how does temperature affect the weather? Warmer air = more water vapor Precipitation Temperature is how hot or cold the air is. Thermometer Temperature
Clouds Cloud formation is affected by temperature and humidity. Types Weather predictors
Air Pressure Air Pressure is the weight of the air. The sun’s role Warmer, lighter, less dense air = lower air pressure Barometer Low pressure = warm temps, rain and storms High pressure = cool temps & clear skies
Wind Wind is the natural movement of air. What causes it? Air moves from ___ pressure to ___ pressure areas. High pressure area close to a low pressure area means the wind will be fast. Big temperature differences in the areas will make wind blow faster.
