topographical features such as mountains and relationship to weather

Mountains Disrupt Air Flow How Does Air Movement Affect Weather? This holds true for mountains and high-elevation plateaus, such as. Weather and climate depends on a lot of variables, including latitude, temperature, At high elevations such as the top of mountains, there is less air above the Earth's using lines called isobars, which are similar to contours on a topographic map. In the Arctic, the common features are the Aleutian Low, Siberian High. The Topography of an area can greatly influence our climate. The position of a town, city or place and its distance from mountains and substantial areas of.

Strong winds can result, such as the powerful and unseasonably warm Chinook winds that flow down the eastern side of the Rocky Mountains. In arctic regions, extremely dense dry air is pulled off the edges of ice sheets by gravity. These forceful rushing winds are known as katabatic or gravity winds.

Mountain passes also act as natural funnels and increase wind speeds. In California, Santa Ana winds blowing off the deserts are enhanced by these breaks.

Wind blows more strongly when forced by topography through a narrow opening, and many wind farms can be found in these locations. First observed by the explorer and naturalist Alexander von Humboldt, air cools at 3.

This is the equivalent of traveling hundreds of miles north, and creates a complex Highland climate with great diversity. Orientation of Topography and Microclimates Ablestock. In the northern hemisphere, south-facing slopes are sunnier and support entirely different ecological communities than north-facing slopes.

The south side of a mountain may experience spring conditions weeks or even months ahead of its north side. Where year-round snow or glaciers exist, they are nurtured by the shade provided by north- and west-facing slopes.

Prevailing global wind patterns There are 3 major wind patterns found in the Northern Hemisphere and also 3 in the Southern Hemisphere. These are average conditions and do not essentially reveal conditions on a particular day.

CLIMATE & WEATHER

As seasons change, the wind patterns shift north or south. So does the intertropical convergence zone, which moves back and forth across the Equator. Sailors called this zone the doldrums because its winds are normally weak.

Polar regions experience the greatest variation, with long periods of limited or no sunlight in winter and up to 24 hours of daylight in the summer. Topography The Topography of an area can greatly influence our climate. Mountain ranges are natural barriers to air movement.

6 Factors Affecting India's Climate

In California, winds off the Pacific ocean carry moisture-laden air toward the coast. The Coastal Range allows for some condensation and light precipitation.

Inland, the taller Sierra Nevada range rings more significant precipitation in the air. On the western slopes of the Sierra Nevada, sinking air warms from compression, clouds evaporate, and dry conditions prevail. Effects of Geography The position of a town, city or place and its distance from mountains and substantial areas of water help determine its prevailing wind patterns and what types of air masses affect it. Coastal areas may enjoy refreshing breezes in summer, when cooler ocean air moves ashore.
