Study Notes
Ethiopian and Horn Climate
- Ethiopia's diverse landscape and location near the equator and Indian Ocean create varied weather patterns.
Weather and Climate
- Weather: The current atmospheric conditions (temperature, pressure, humidity, wind, cloudiness, precipitation).
- Climate: The long-term average weather conditions over an extended period.
Elements and Controls of Weather and Climate
- Elements include temperature, precipitation, humidity, winds, and air pressure.
- Controls are factors influencing these elements, including latitude, land/water distribution, winds/air pressure, altitude, and ocean currents.
Latitude
- Ethiopia's latitude leads to high average temperatures, small annual temperature ranges, and minimal seasonal variations in day length.
- Latitude affects solar insolation and temperature.
Inclination of the Earth's Axis and Seasons
- The Earth's tilted axis causes seasonal changes (day length variations).
- Equinoxes: Equal day and night (around March 21 and September 23).
- Solstices: Longest (June 21) and shortest (December 22) days in the Northern Hemisphere.
Altitude and Lapse Rates
- Altitude: Height above sea level.
- Temperature Change: Generally, temperature decreases with increasing altitude.
-
Lapse Rate: The rate of temperature change with altitude.
- Normal Lapse Rate: 6.5°C per kilometer (in the troposphere).
- Dry Adiabatic Lapse Rate: 10°C per 1,000 meters (unsaturated air).
- Wet Adiabatic Lapse Rate: ~5°C per 1,000 meters (saturated air).
- Environmental Lapse Rate: The actual observed temperature change with altitude in the atmosphere, often ~6.5°C per 1,000 meters, but can vary due to inversions.
