- Latitude:
- Temperature: Generally decreases from the equator (0°) towards the poles (90°). The equator receives more direct sunlight year-round, leading to higher average temperatures. The poles receive less direct sunlight and have lower average temperatures.
- Precipitation: Highest near the equator (tropical rainforests) due to intense solar heating causing air to rise and cool, forming clouds and rain. Precipitation is also high in the mid-latitudes (around 45°-60°) due to prevailing westerlies and frontal systems. It is generally low in the subtropical zones (around 20°-30°) and at the poles.
- Can two places at the same latitude have a different climate?
- Yes. Climate is influenced by many factors besides latitude, including altitude, proximity to large bodies of water, ocean currents, prevailing winds, and topography (like mountain ranges). For example, a coastal city and an inland city at the same latitude can have very different temperature and precipitation patterns.
- Windward vs. Leeward of Mountain Ranges:
- Windward:
- Temperature: Cooler than the leeward side because moist air rises, expands, and cools as it climbs the mountain.
- Precipitation: Higher. As the moist air cools on the windward slope, water vapor condenses, leading to frequent cloud formation and heavy rainfall or snowfall.
- Leeward:
- Temperature: Warmer than the windward side because descending air compresses and warms (rain shadow effect).
- Precipitation: Much lower. The air has lost most of its moisture on the windward side, resulting in dry conditions on the leeward side.
- What conclusions can we draw about the heating/cooling of land and water on Earth?
- Land heats up and cools down much faster than water. This difference leads to distinct temperature patterns between coastal and inland areas. Water's high heat capacity moderates coastal climates, making them milder with smaller temperature variations compared to inland areas, which experience greater extremes. This differential heating also drives local wind patterns, such as sea breezes during the day and land breezes at night.
