Study Notes
Climate Classification
-
Köppen Climate Classification: most widely used system, categorizes climates into 5 main groups:
- A: Tropical climates
- B: Dry climates
- C: Temperate climates
- D: Continental climates
- E: Polar climates
-
Climate zones: classified based on temperature, precipitation, and other factors
- Tropical
- Desert
- Temperate
- Polar
- Alpine
Humidity Measurement
- Relative Humidity (RH): percentage of water vapor in air compared to saturation point
- Absolute Humidity: total amount of water vapor in air
- Dew Point Temperature: temperature at which air becomes saturated with water vapor
- Hygrometer: instrument used to measure humidity
Weather Forecasting
- Numerical Weather Prediction (NWP): uses computer models to forecast weather
- Nowcasting: short-term forecasting (0-2 hours) using current weather conditions
- Synoptic Scale Forecasting: forecasting on a larger scale (days to weeks)
- Mesoscale Forecasting: forecasting on a smaller scale (hours to days)
Atmospheric Layers
- Troposphere: lowest layer, extends up to 12 km, where weather occurs
- Stratosphere: next layer, up to 50 km, where ozone layer is located
- Mesosphere: layer above stratosphere, up to 80 km
- Thermosphere: layer above mesosphere, up to 600 km
- Exosphere: outermost layer, where atmosphere interacts with space
Frontal Systems
- Cold Front: boundary between cold and warm air masses, brings cooler temperatures
- Warm Front: boundary between warm and cold air masses, brings warmer temperatures
- Stationary Front: boundary between air masses with little movement
- Occluded Front: cold front overtakes warm front, leading to a new cold front
Greenhouse Effect/Ozone Depletion
- Greenhouse Effect: trapping of heat by atmospheric gases, leading to global warming
- Ozone Depletion: reduction of ozone layer due to CFCs and other pollutants
- Ozone Hole: thinning of ozone layer over Antarctica
Weather Instruments and Their Functions
- Barometer: measures air pressure
- Hygrometer: measures humidity
- Anemometer: measures wind speed and direction
- Rain Gauge: measures precipitation
- Thermometer: measures temperature
- Weather Vane: indicates wind direction
Air Pressure and Applications
- Atmospheric Pressure: pressure exerted by air on the Earth's surface
- Air Pressure Gradient: change in pressure over distance, driving wind
- Isobars: lines on a map connecting points of equal pressure
- Weather Forecasting: air pressure is used to predict weather patterns
- Aviation: air pressure is used to determine aircraft altitude and navigation
