how jet streams are formed?
482506
A jet stream forms high in the upper troposphere between two air masses of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream. ... Since it is horizontal air pressure differences that cause wind, this leads to very strong winds.

The strongest jet streams are the polar jets, at 9–12 km (30,000–39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10–16 km (33,000–52,000 ft). The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet.

Wadis have braided stream patterns because of the deficiency of water and the abundance of sediments. Water percolates down into the stream bed, causing an abrupt loss of energy and resulting in vast deposition. Wadis may develop dams of sediment that change the stream patterns in the next flash flood.

A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. ... As small creeks flow downhill they merge to form larger streams and rivers. Rivers eventually end up flowing into the oceans. If water flows to a place that is surrounded by higher land on all sides, a lake will form.

From what I can tell, they are formed when there's rising air that creates wide-spread cloud cover, together with wind shear that blows across the rising air. This can set up gravity waves, where air moves up and down as buoyancy and gravity battle it out, creating long rippling waves that carry the clouds up and down.

How do cumulonimbus clouds form? Cumulonimbus clouds are born through convection, often growing from small cumulus clouds over a hot surface. They get taller and taller until they represent huge powerhouses, storing the same amount of energy as 10 Hiroshima-sized atom bombs.

Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. ... Air currents flow in the atmosphere, the layers of air surrounding the Earth.

They form when turbulent vertical currents meet a cirrus layer, creating the puffy cumulus shape. Cirrocumulus clouds can also form through contrails, the vapour trails left by planes as they fly through a dry upper troposphere. These streaks can spread out and become cirrus, cirrostratus and cirrocumulus.

The noise from a jet comes from two sources – the engine itself and the reaction the exhaust has with the surrounding air. A jet engine works by taking in air through the intake and compressing it as much as 12 times its original pressure. ... In layman's terms, the louder the jet the less efficient it is.

Aeolian landforms are formed when wind moves sediment (see aeolian processes). Sediment particles move when they are lifted by upwards Bernoulli forces that exceed their downwards weight.

The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.

Jet streams are located about five to nine miles above Earth's surface in the mid to upper troposphere — the layer of Earth's atmosphere where we live and breathe. Airplanes also fly in the mid to upper troposphere.

A delta is formed when the river deposits its material faster than the sea can remove it. ... Arcuate or fan-shaped - the land around the river mouth arches out into the sea and the river splits many times on the way to the sea, creating a fan effect.

Clouds form when water vapor 'condenses' around small particles in the air. Precipitation occurs when the products of condensation coalesce to form water droplets that are too heavy to be supported by the upward motion of the air. The water droplets fall to Earth's surface as rain, or snow.

Jet is a product of high-pressure decomposition of wood from millions of years ago, commonly the wood of trees of the family Araucariaceae. Jet is found in two forms, hard and soft. Hard jet is the result of carbon compression and salt water; soft jet is the result of carbon compression and fresh water.

The jet stream refers to a narrow current of strong westerly winds in the upper troposphere. The polar easterlies refers to an easterly wind belt found between the weak polar anticyclone and the westerly depression. The trade winds are predominately easterly winds that blow steadily over the ocean areas.

Hurricanes are formed over warm water in tropical oceans while tornadoes are formed over land. Hurricanes develop when they are far away from a jet stream and tornadoes are formed within storms very close to those jet streams.
