Earth’s Climatic Regions

These flashcards cover key vocabulary terms related to Earth's climatic regions, weather and climate differences, and the mechanisms influencing precipitation.

Weather

Short-term conditions such as temperature, humidity, and precipitation.

Climate

Average weather conditions over a long period of time.

Insolation

Incoming solar radiation that influences temperature.

Latitude

The geographic coordinate that affects climate due to the angle of sunlight.

Temperature Controls

Factors influencing temperature including latitude, altitude, cloud cover, and land/water distribution.

Orographic Lifting

Precipitation mechanism where moist air rises over mountains.

Hadley Cells

Atmospheric circulation cells that produce high pressure and desert conditions in subtropical regions.

ITCZ (Intertropical Convergence Zone)

A zone of converging trade winds near the equator, influencing rainfall patterns.

Mesothermal Climates

Mild winter climates with true seasonality, characterized by changing air masses.

Microthermal Climates

Cold winter climates typically found in mid to high latitudes.

Polar Climatic Regions

Areas with extremely cold temperatures and limited vegetation.

Desert Climates

Regions where moisture demand exceeds supply, resulting in arid conditions.

Tropical Rainforest

A climate zone characterized by constant moisture and high precipitation throughout the year.

Tropical Savanna

Climate with distinct wet and dry seasons, typically found in low latitudes.

Subarctic Climates

Cold climates with short summers and very cold winters.

Seasonality

Variation in climatic conditions throughout the year, allowing for distinct seasons.

Precipitation Mechanisms

Processes that lead to rainfall, including convergent, convectional, orographic, and frontal lifting.
