Weather and Climate Concepts

Front

Warm front

Back

The leading edge of a warm air mass that is replacing a cooler air mass. It signifies a transition toward warmer, more humid conditions, with the warm air gradually sliding over the cooler, denser air.

Front

Cold front

Back

A weather phenomenon in which a mass of cold, dense air advances and replaces a warmer air mass. It is characterized by a distinct change in temperature, wind direction, and often precipitation, as the cold air wedges under the warmer air, forcing it upward.

Front

Occluded front

Back

Forms when a warm air mass gets caught between two cold air masses. Large masses of warm air and cold air meet but do not mix because of differences in density.

Front

Stationary front

Back

A weather front where neither the warm nor the cold air mass is advancing, resulting in a boundary that remains relatively fixed or moves very slowly. This can lead to prolonged periods of consistent weather conditions, often characterized by cloudy skies and precipitation.

Front

Continental biome

Back

A climate characterized by significant temperature differences between seasons, with hot summers and cold winters. Typically found in the interior regions of continents, far from the moderating influence of oceans, it is known for low humidity and relatively low precipitation levels.

Front

Marine biome

Back

The largest biome on Earth, characterized by its salty water and covering approximately 70% of the planet's surface. It encompasses various interconnected ecosystems such as oceans, coral reefs, and estuaries.

Front

Arctic biome

Back

A vast, treeless area characterized by extremely cold temperatures, low precipitation, and permanently frozen ground (permafrost). It experiences long, dark winters and short, cool summers, with a limited growing season.

Front

Polar biome

Back

Characterized by extremely cold temperatures, little precipitation, and limited sunlight. Primarily found in the Arctic and Antarctic regions, it is dominated by ice and snow, with limited plant and animal life.

Front

Tropical biome

Back

A region near the equator characterized by consistently warm temperatures and high precipitation, supporting a wide variety of plant and animal life. It is known for high biodiversity and distinct layers of vegetation.

Front

Weather conditions

Back

Includes precipitation, sunshine, fog, floods, tornadoes, hurricanes, lightning, thunderstorms, sandstorms, humidity, wind, etc.
