Climate refers to the characteristic weather patterns of a region, shaped by factors such as temperature, precipitation, air pressure, humidity, and sunshine. Latitude plays a crucial role in determining climate; areas near the equator receive more solar energy, resulting in hotter temperatures, while polar regions remain cold due to low-angle solar radiation. Additionally, topographic features like large bodies of water and mountains significantly influence local climates, moderating temperatures and creating diverse weather patterns, including desert formation on leeward sides of mountains.

What is Climate? Section 16.1 Pg. 452-455
Climate • Is the characteristic weather of a region • Includes: temperature, precipitation, air pressure, humidity, and days of sunshine
Latitude affects climate Solar energy received at a location depends on the tilt of the Earth. Latitude closest to equator gets the most sun.
Latitude affects climate • Polar zones: • Radiation hit poles at low angles. Ice reflects radiation, so its never warm there.
Latitude affects climate • Tropics: • Close to equator • Always hot, except at high elevation
Latitude affects climate • Temperate Zones: • Ex. Continental United States • Temperature is moderate
Topographic Features Affect Climate • Large bodies of water affect costal areas by making it cooler in the summer and warm in winter • Large cities are warmer because buildings and streets absorb radiation
Topographic Features Affect Climate • Mountains: • Colder in the mountains than at sea level • On one side of the mountain there is wind, air rises, cools, and drops its moisture as precipitation • On the other side , the air descends, heats up, and dries out the land, often forming deserts.
