Jet Stream and Intro to Jet Streak Dynamics

Hey everyone!
Sorry for the long wait but here it is, the Jet Stream. Unfortunately, this will have to be a short blog, since I don't have much free time. Anyhow, jet streak dynamics is an interesting weather phenomenon that is being studied today. The jet stream plays a big role in the development of storms. Below is an expanded explanation about the role of the jet stream and what jet streaks really are.




As well below is the US-NAM 500mb model from 00Z, Saturday May 28, 2011 to 12Z, Sunday May 29, 2011. Notice that on the 12Z, Sunday May 29, 2011 NAM model we can see a trough over South Central California and Western Nevada.  This area is associated with having the maximum winds found in the jet stream. So keeping this in mind, a new low pressure system might bring some new storms into Monday, but some more analysis (for another blog) needs to be done to determine storm development and intensity.



My next blog will deal with the tornado outbreaks that have ravaged  parts of Oklahoma and Missouri, including some explanations on thunderstorm and tornado development, so stay tuned!
