Jet stream forecast united states.

There are two basic types of MOS, short range and long range. The short-range MOS guidance is generated every six hours (0000, 0600, 1200, and 1800 UTC) from the Global Forecast System (GFS) and North American (NAM) models. Forecast elements are valid from 6 to 72 hours in advance for 3- or 6-hour increments.Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere's polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere. The jet is created by the convergence of cold air masses descending from the Arctic and rising warm air from the tropics. Deep troughs and steep ridges emerge as the denser cold air sinks ...The jet stream is a large and powerful stream of air (wind) at around 8-11km (5-7mi) altitude. Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase (La Nina). That usually redirects the polar jet stream down over the northern United States.Looking at the pressure anomaly forecast, you can see a strong high-pressure system in the North Pacific, resulting from the active La Nina.
