Study Notes
Weather Radar
- Uses radio waves to detect precipitation and other weather phenomena
- Types of weather radar:
- Pulse radar: emits high-powered pulses of radio energy
- Doppler radar: measures velocity of particles in the atmosphere
- Phased array radar: uses electronic scanning to steer the beam
- Radar frequencies:
- S-band (2-4 GHz): used for precipitation detection
- C-band (5-7 GHz): used for wind profiling and tornado detection
- X-band (8-12 GHz): used for high-resolution precipitation detection
- Radar applications:
- Precipitation forecasting
- Severe weather warning
- Aviation weather forecasting
- Hydrological forecasting
Meteorological Instrumentation
- Surface weather observation stations:
- Measure temperature, humidity, wind direction, wind speed, and atmospheric pressure
- Can be automated or manual
- Upper air observation stations:
- Use radiosondes to measure temperature, humidity, and wind speed aloft
- Launched using balloons or aircraft
- Remote sensing instruments:
- Satellites: measure cloud top temperature, humidity, and wind speed
- Radiosondes: measure atmospheric conditions aloft
- Radar: measures precipitation and wind velocity
- Specialized instruments:
- Anemometers: measure wind speed and direction
- Barometers: measure atmospheric pressure
- Hygrometers: measure humidity
Maritime Related
