1 Elements of Weather Measuring Weather

2 What are the Basic Elements of Weather & Climate (go outside and list 6) Wind: speed and direction Temperature: of air Humidity Clouds: type and amount Precipitation: type and amount Air Pressure Measured on a regular (daily) basis. They are inter- related: Change in one produces a change in the others

12 Automated Surface Observing System ASOS Joint program between the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). ASOS detects significant changes 24/7,Measures: Sky condition: up to 12,000 feet Visibility (to at least 10 statute miles) Precipitation: type and intensity Obstructions to vision: fog, haze Air Pressure: sea-level and local altitude Ambient temperature, dew point temp. Wind: direction, speed and character
