--- Quote ---I thought I'd make a topic for this. I'll be posting some graphics daily at around the same time, or at least the images will be. Help out with whatever... talk about weather events as well here... I don't want to hog every post in this topic.

In today's I don't really know what 5 is doing but it might be a bit subtropical (on visible and IR wavelengths)? I'm no expert, but I guess we'll just have to watch and wait.

Upper level lows - My knowledge of water vapor imagery interpretation

I intend to turn this into a rightfully compiled list of official data sources as well as my personal graphic for it, but I will have a personal touch, for example, any anomalies in the data (missed subtropical cyclones, other interesting bits). I don't know how legit this will be if I find a subtropical cyclone or something and wikipedia or something needs a source, or anything. We'll have to see how this turns out in the next few days and what I decide to do with it.

Pacific Windstorm Name List [PDF] (has name origins and contributors and looks nice)

Windstorm Track File - for editing best tracks and updating

some useful sources would be http://manati.star.nesdis.noaa.gov/datasets/ASCATData.php/ASCATData.php, CIMSS' satellite derived windspeeds, and the Ocean Prediction Center

this post explains how to use McIDAS V.

Definition of a nameable extratropical cyclone:
1. It must have winds at or above 35kt in its near vicinity.
2. It must have a low pressure center.
3. The low's outermost closed isobar must be 8 hPa higher than the minimum at the center.
4. It must be within the Northeast Pacific basin*.
5. Exceptions may be made for storms near the Northeast Pacific basin that are already notable.

*Definition of the Northeast Pacific basin: It is the region of ocean between 180° and 110°W, 20°N and the continental divide of North America, and the Bering Sea west of 180°.

Darvince:
hey you said you're gonna do this this winter gogogogo

atomic7732:
it no is winter tho

Darvince:
extratropicals exist all year
