Unit 4: Climates and Biomes

The state of the atmosphere with respect to wind,temperature, cloudiness, moisture, pressure, etc.

The composite or generally prevailing weather conditions of a region as temperature, air pressure, humidity, precipitation,sunshine, cloudiness, and winds, throughout the year,averaged over a series of years.

The dense surface water is drawn away from along a shore by offshorecurrents and replaced by cold, denser water brought up from the subsurface.

An irregularly recurring flow of unusually warm surface waters from the Pacific Ocean toward and along the western coast of South America that prevents upwelling of nutrient-rich cold deep water and that disrupts typical regional and global weather patterns

An irregularly recurring upwelling of unusually cold water to the ocean surface along the western coast of South America that often occurs following an El Niño and that disrupts typical regional and global weather patterns especially in a manner opposite to that of El Niño

An advancing edge of a cold air mass

An advancing edge of a warm air mass

The temperature at which a vapor (as water) begins or would begin to condense

Low precipitation on the far side (leeward side) of a mountain when prevailing winds flow up and over a high mountains or range of high mountains.

The essentially uniform local climate of a usually small site or habitat

Extent or distance from side to side extent or distance from side to side

The vertical elevation of an object above a surface (as sea level or land) of a planet or natural satellite

Daytime temperatures are high in summer and low in winter and there is more precipitation.

Vegetation is sparse, winters are cold, summers are warm or hot and precipitation is low

biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Grasslands are dominated by grass and other herbaceous plants. Savannas are grasslands with scattered trees
