Discovery of the Jet Stream

Did Wiley Post discover the jet stream?

What created the jet stream?

What Causes Jet Streams? Jet streams form when warm air masses meet cold air masses in the atmosphere. The Sun doesn’t heat the whole Earth evenly. That’s why areas near the equator are hot and areas near the poles are cold.

When was the term jet stream first used?

Why is it called jet stream?

Jet streams were first discovered in the 1920s by a Japanese meteorologist named Wasaburo Ooishi. He used weather balloons to track upper level winds high above Mount Fuji. The term “jet stream” wasn’t used until 1939 though when a German meteorologist first used the term in a research paper.

What did Wiley Post invent?

Wiley Hardeman Post (November 22 1898 – August 15 1935) was a famed American aviator during the interwar period and the first pilot to fly solo around the world. Also known for his work in high-altitude flying Post helped develop one of the first pressure suits and discovered the jet stream.

What happened to Wiley Post’s eye?

He lost his left eye in a rig accident in 1926 and used the injury settlement money to buy his first plane. Oilman Florence Hall hired Post as a pilot and he went on to set flying records in the Winnie Mae named after Hall’s daughter.

Do planes fly in the jet stream?

The high-altitude winds exist in both the northern and southern hemispheres and consist of a subtropical jet stream as well as a polar jet stream where wind speeds can top out at 275 miles per hour. … In the early 20th Century the jet stream would change the game for planes flying from west to east.

What would happen if an airplane flew against a jet stream?

Besides a local weather storm turbulence to an airplane may be caused by a plane flying into or out of a jet stream. … The wind currents along the edges of the jet stream are choppy or turbulent as high-speed air meets more slowly moving nearly stationary air (about 20 m.p.h.).

How many jet streams exist in each hemisphere?


Each hemisphere has two primary jet streams — a polar and a subtropical. The polar jet streams form between the latitudes of 50 and 60 degrees north and south of the equator and the subtropical jet stream is closer to the equator and takes shape at latitudes of 20 to 30 degrees.

Why are jet streams curved?

These winds are called jet streams. … The wind bends because of the Earth’s movement: instead of simply moving from cold to warm areas it is deflected by the Coriolis force generated by the rotation of the planet and moves along the boundaries of air masses.

How are jet streams formed Upsc?

Jet Streams develop where air masses of differing temperatures meet. … Greater the difference in temperature faster is the wind velocity inside the jet stream. Jet Streams extend from 20 degrees latitude to the poles in both hemispheres.

What are the two main jet streams?

At most times in the Northern and Southern Hemispheres there are two jet streams: a subtropical jet stream centered at about 30 degrees latitude and a polar-front jet stream whose position varies with the boundary between polar and temperate air.

How much is a JetStream?

Depending on numerous factors the average price for a pre-owned BAE Jetstream S31/32 is $515 050.00. A $257 525.00 loan over 120 months including $1073.02 per month in interest equates to a $12 913.26 per-period payment.

How is the jet stream often defined?

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.

Why is the jet stream so far south?

Earth is split into two hemispheres and air is constantly moving around to spread heat and energy from the equator to the poles. … Therefore the jet stream exists largely because of a difference in heat which in the northern hemisphere means cold air on the northern side of the jet stream and warm air to the south.

What does the tropopause do?

The tropopause is the boundary that demarcates the troposphere from the stratosphere and is the part of the atmosphere where there occurs an abrupt change in the environmental lapse rate (ELR) from a positive rate in the troposphere to a negative rate in the stratosphere.

What happens to jet streams as they get closer to the equator?

They blow faster. They do not change.

Do all cyclones develop an eye?

Extra-tropical cyclones may not always have an eye whereas mostly mature storms have well-developed eyes. Rapidly intensifying storms may develop an extremely small clear and circular eye sometimes referred to as a pinhole eye.

Why do planes not fly over the Pacific?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather it’s spherical. As a result straight routes don’t offer the shortest distance between two locations.

Why would a pilot want to catch a jet stream?

Commercial airline pilots have used jet streams since 1952 when a Pan Am flight flew from Tokyo to Honolulu at 25 000 feet in order to take advantage of one. By flying in a jet stream planes traveling from west to east get a significant boost from the tailwind which saves time and fuel.

What happens if a plane goes too high?

When the plane gets too high there is insufficient oxygen to fuel the engines. “The air is less dense at altitude so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
