Jet streams

I will try to pass the TOEFL test within 6 days, so I hope that you can prove some of my paper.

So this is the first wind about a specific type called "jet stream". And it was discussed in paragraph and lecture.

Due to the temperature gradient between the tropospheric warmth and the earth's surface heat, the jet is a strong wind. The strength of this gas flow is usually a direct cause of the strength of the temperature difference. Wind speeds are classified as rapids of 57 miles per hour or more, but some may reach 300 miles per hour.

There are mainly two types of wind patterns in the area between the equator and the North Pole. The subtropical river is in the southern part of the United States. Extraordinary rapids occur in Idaho and Mantana states. According to the lecture, when the American winter is cold this creek may even extend to Texas.

Several torrents have a major impact on the movement of the aircraft. As the professor said, flying in the direction of the jet will cause more time for the aircraft to reach the target. Delay may reach several hours. In addition, if the wind blows in front of the aircraft, demand for fuel increases and turbulence may occur. "

Because of the temperature gradient between the tropospheric warmth and the earth's surface heat, the jet stream is a strong wind blowing strongly. The strength of this gas flow is usually the direct cause of direct temperature difference. The wind is classified as a rapid stream with a speed of over 57 miles per hour, but it can even reach as much as 300 miles per hour.

There are mainly two types of wind patterns in the area between the equator and the North Pole. The subtropical river is in the southern part of the United States. In Idaho State and Montana State, extreme rapids occur. According to the lecturer, this trend will sometimes extend to Texas when the United States gets cold winter.

Delay may reach several hours. Sometimes it will take hours or maybe several hours. In addition, if the wind blows in front of the aircraft, demand for fuel increases and turbulence may occur. "

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.

Polar jets are formed by air movement. These movements are related to the cold front. The cold front separates the air before the cold from the north and the warm moist air separates from the south. Extreme rapid flow plays a role in the development of storm and tends to cause storm. Steering is the reflection of a very strong air mass (such as a jet). Subtropical jets tend to develop during the winter and are formed by the movement of tropical and subtropical air related to the severe temperature gradient in the middle troposphere. It usually involves a period of intense convection rainfall. It is weak, it does not cause a whirlwind of transition. This rapid flow helps the occurrence and suppression of storms and disturbances. Typically, the jet contains jet fringes due to wind portions higher than the surrounding wind speed due to a strong temperature gradient.
