Biology Definition Jet Stream

On Earth the main jet streams are located near the altitude of the tropopause and are westerly winds flowing west to east. A long narrow meandering current of high-speed winds near the tropopause blowing from a generally westerly direction and often exceeding a speed of 250 miles 402 kilometers per hour Examples of jet stream in a Sentence.

Jet streams are very fast moving currents of air found at about 10 km 62 miles above the surface of the earth in the tropopause which is the transition layer between the Earths troposphere and the stratosphere.

Biology definition jet stream. Jet streams are several hundreds of miles long and less than one mile thick. Definition of jet stream. A jet stream is a type of air current that forms high in the atmosphere.

Jet streams on earth are westerly winds as in flowing west to east and may start stop and split into two or more streams. And to make the atmospheric forces balance the motion the jet stream is a strong wind that forms to do just that. Jet streams are characterized by wind motions that generate strong vertical shearing action which is thought to be largely responsible for clear air turbulence.

Their paths typically have a meandering shape. Blocking events occur when one of the jet streams fast-flowing air currents traveling around the Earth in the upper part of the tropospherepinches off large masses of air from the normal wind flow for an extended period. Jet streams are very fast moving air currents flowing in narrow paths in the Earths atmosphere.

So you get around the whole northern hemisphere. Biology is the broadly based study of living organisms and has become an increasingly dynamic and wide-ranging discipline. A jet stream is defined as a current of rapidly moving air that is usually several thousand miles long and wide but is relatively thin.

A type of air current. Jet streams are fast flowing narrow meandering air currents in the atmospheres of some planets including Earth. Jet streams form in a region between the troposphere and the stratosphere called the tropopause situated between 10 and 14 km 6-9 miles above the surface of the Earth.

Specifically jet streams are currents of fast moving air high in the atmosphere that can reach. Biology For and terms of write G next to. A jet stream is a band of wind thats high up in the atmosphere.

The atmosphere which you might think of as the air is actually the collection of gases that surround the Earth. Biology Dictionary Definition Vocabularycom. Jet streams are caused by a combination of a planets rotation on its axis and atmospheric heating by solar radiation and on some planets other than Earth internal heat.

They move eastward at altitudes of about 8 to 15 kilometers 5 to 9 miles. JET STREAM meaning - JET STREAM definition - JET STREAM explanationSo. D diffusion E experiment F fossil G geology H heat I interference J jet stream K kinetic L latitude M motion N neutron O oxygen P physics Q quasar R respiration S solar system T thermometer U.

There are usually four distinct jet streams two each in the Northern and Southern hemispheres. These kinks in the jet stream typically last at least five days but can persist for weeks. An air current is a flowing movement of air within a larger body of air.

Jet stream wind speeds average 56 km 34 mi per hour in the summer and 120 km 74 mi in the winter. The Sun heats Earth unevenly creating masses of colder air near the poles and warmer air near the equator. Jet streams are like rivers of air in the atmosphere where air currents travel at high speeds.

The major jet streams usually follow an undulating narrow path from west to east. What does JET STREAM mean. Jet streams are currents of air high above the Earth.

Jet streams are fast flowing narrow meandering air currents in the atmosphere of the Earth. They are found in the upper levels of Earths atmosphere at the tropopause - the boundary between the troposphere and stratosphere see atmospheric layers. Jet stream A narrow current of strong wind circling the Earth from west to east at altitudes of about 11 to 13 km 7 to 8 mi above sea level.

Jet stream a region of long narrow high-speed winds that typically flow northeastward eastward and southeastward in the middle and upper troposphere or lower stratosphere. The aim is to elucidate general principles applicable to many different sorts of organisms. They form where large temperature differences exist in the atmosphere.

It may be approached by focus on cell and molecular processes development organismal physiology and morphology natural history evolution conservation or ecology. Biology Vocabulary List Flashcards Quizlet.
