Factors and Types of Climate

Factors Affecting Climate

• Latitude influences solar energy intensity; as latitude increases, solar energy intensity decreases.
• Near the equator, the sun's rays strike the planet at nearly right angles, resulting in more intense solar energy.
• As latitude increases, the average annual temperature decreases.

Types of Climate

• Tropical Zone: Located between 23.5° north and 23.5° south of the equator; characterized by consistently high temperatures throughout the year. Average temperatures typically exceed 64° Fahrenheit (18° Celsius).

• Dry/Arid Climates: Characterized by a lack of precipitation throughout the year. Examples include deserts like the Sahara.

• Temperate Zone: Located between 23.5° and 66.5° north and south of the equator; experiences hot summers and cold winters. Temperatures are generally higher than 50° Fahrenheit (10° Celsius) during warm months, and above 27° Fahrenheit (3° Celsius) during cold months.

• Polar Zone: Located between 66.5° north and south of the equator, encompassing the poles. Experiences extremely cold temperatures year-round, with very cold summers and winters. Examples include Antarctica and the North Pole.

Closeness to Large Bodies of Water

• Large bodies of water (lakes and oceans) affect local temperatures by moderating them.
• Places downwind of large bodies of water typically have cooler summers and milder winters compared to inland areas at the same latitude.
• Water moderates temperatures; cool summers, warmer winters.

Topography

• Topographic features (mountains) significantly influence precipitation patterns.
• Heavy precipitation often occurs on the windward side of mountains.
• Air losing moisture on the leeward side of mountains creates a "rain shadow."
• Rain shadows can extend hundreds of kilometers downwind from mountain ranges.
• The Orographic Effect results in cool, moist air on the windward side of a mountain range and warm, dry air on the leeward side.

Elevation

• Air temperature decreases with elevation at an average rate of ~6.5° Celsius per 1000 meters.
• Higher elevations result in cooler climates.
• Elevation also impacts the amount of precipitation an area receives.
• The temperature of the atmosphere drops 3 degrees Fahrenheit for every 1000 feet increase in elevation.

Atmospheric Circulation

• Global winds play a key role in distributing heat and moisture around Earth.
• Winds move warm air toward the poles and cool air toward the equator.
• Low-pressure zones at the equator and subpolar regions contribute to cloud formation and precipitation.

Vegetation

• Plant types depend on climate.
• Vegetation affects both temperature and precipitation patterns.
• Vegetation influences how much solar energy is absorbed and released (affecting temperature).
• Transpiration (release of water vapor from plants) influences precipitation levels.
