Study Notes
Hills and Summer Temperature
- Hills tend to be cooler in summer due to higher elevation, which leads to lower air pressure and temperatures.
- Increased vegetation and moisture in hilly areas also contribute to cooler microclimates.
Moderating Influence of the Sea
- Oceans regulate temperature by absorbing heat during the day and releasing it at night, resulting in milder climates.
- Proximity to the sea often leads to less extreme weather and temperature fluctuations compared to continental locations.
Continentality Factor
- Continentality refers to the proximity to large landmasses or oceans, affecting temperature variation and precipitation patterns.
- Areas farther from oceans experience greater temperature extremes between summer and winter.
High Mountains and Climate
- High mountains influence climate by blocking prevailing winds, creating rain shadows on one side and increased moisture on the other.
- They can also affect temperature, as high altitudes generally experience cooler conditions.
Ocean Currents and Coastal Climate
- Ocean currents distribute heat across the globe, influencing coastal temperatures and weather patterns.
- Warm currents raise temperatures along coastlines, while cold currents lower them, impacting local climates.
Precipitation
- Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.
- It is a crucial component of the water cycle, affecting ecosystems and agriculture.
Weather vs. Climate
- Weather refers to short-term atmospheric conditions, including temperature, humidity, precipitation, and wind at a specific time and place.
- Climate is the long-term average of weather patterns over an extended period (typically 30 years) in a particular region.
Elements of Weather and Climate
- Weather elements include temperature, humidity, atmospheric pressure, wind speed, and precipitation.
- Climate encompasses long-term trends and averages of these weather elements, highlighting regional patterns over decades.
Latitude and Climate
- Latitude significantly affects climate; locations closer to the equator receive more direct sunlight, resulting in warmer temperatures.
- As latitude increases towards the poles, solar energy decreases, leading to cooler climates.
Altitude and Climate
- Higher altitudes usually result in cooler temperatures due to the thinning atmosphere and lesser air pressure.
- Altitude can also influence precipitation patterns, with mountains often receiving more rainfall at higher elevations.
Temperature Gradient from Equator to Poles
- Air temperature decreases from the equator to the poles due to variations in solar insolation, affecting heating of the Earth's surface.
- The angle of sunlight striking the Earth is more direct at the equator and more oblique at higher latitudes, leading to cooler conditions.
Seasonal Divisions
- The primary factor determining seasonal divisions is the tilt of the Earth's axis, which affects the distribution of sunlight throughout the year.
- Changes in day length and solar heating define the seasonal variations experienced in different regions.
