What is the Jet Stream and why is it important?

The jet is a strong wind and usually blows a narrow band on the upper atmosphere. Normally, the jet blows from the west to the east, but their flow tends to move north and south. Wind flow follows the limits of hot and cold air

In the winter, the boundary between hot and cold air becomes clearer, so in the winter of the northern hemisphere and the southern hemisphere, the flow of jet is the strongest.

Since the jet is an air mass distributor, the movement of the jet in the south or north moves hot air further north or south relative to the shift. By understanding the motion of the jet, the meter can predict the movement of warm air and cold air, and movement of high pressure and low pressure system. Tracking these moves can predict serious weather events, disasters such as droughts and floods. Predicting these events in a timely and accurate manner makes it possible for the affected countries to receive humanitarian assistance and protect their wealth.

Jet flow reduces fuel consumption and flight time, so it is important for commercial airlines. With the help of a strong wind, the aircraft can ride the wind, reducing the amount of jet fuel needed to propel the aircraft and the time required to reduce air resistance.

Weather patterns around the world are changing all the time. These changes are caused by constantly changing torrents that have also contributed significantly to serious weather events such as floods and droughts. Therefore, to predict the weather from the intensity and position of the air current, the jet is very important. According to research, the weather is relatively homogeneous and not violent in areas without jet air currents. When Polarjet moves to the south, precipitation with storm usually increases in certain areas. Likewise, as the polar jets move north, the dry season occurs in certain areas. Therefore, in order to monitor the weather around the world, it is necessary to understand the continuous tracking of jet airflow and meteorologist movement.

Meteorologists now understand that the course of the jet is to direct the cyclone system to the atmosphere of low pressure. Knowing their course has become an important part of the weather forecast. Jet also plays an important role in the creation of a supercell which is a storm system that creates a tornado (Haby). Jet flow is an important element in our travel patterns and weather conditions

Jet is said to play a very important role in controlling the behavior of the Earth's atmosphere. Meteorologists do not recognize changes in jet form or characteristics, but there is a close relationship between the jet and the weather on the ground. However, the exact nature of this relationship is not yet clear

This jet stands for "tropospheric pole jet", it moves at high speed in the atmosphere where weather occurs and the jet fly. This jet is formed along the boundary between warm air and cold air and becomes more prominent in the winter when the northern hemisphere and air masses of midlatitude form strong contrast with each other. The polar vortex or stratospheric jet is a broad area of ​​low pressure and cold that surrounds the poles of the earth. For example, in the cold winter of 2013/2014 and 2014/2015, you can send the cold Arctic air to Central and Eastern United States, Texas, Mississippi and Alabama. In the winter, the expansion and movement of the polar vortex occurs to various degrees.
