These weather sites have been collected by our members as we monitor both weather conditions and incoming tropical storms.

General weather, wind patterns, weather predictions (models).

First this place, they monitor Typhoons and have historical data and tracks-
http://agora.ex.nii.ac.jp/digital-typhoon/
They are also monitoring and predicting (with computer modeling) the wind patterns around the Fukushima plant.
Simple version(Tiled-10m height only);
http://agora.ex.nii.ac.jp/earthquake/201103-eastjapan/weather/gpv/wind/
Advanced version (Marker-variable height 10m-16,000m);
http://agora.ex.nii.ac.jp/earthquake/201103-eastjapan/weather/gpv/wind/marker/
allows user to change to different Atmospheric levels(10m-16,000m) to see what is going on up higher with the wind.
Real-time monitoring located here;
http://agora.ex.nii.ac.jp/digital-typhoon/ameras/wind-maps/?37.421389,141.033611,8
These guys also have some good information on Typhoons from the past and will no doubt become very handy in the future. The links already posted here are also a good start (Jap MET & JTWC).

Modeling(weather prediction);
A good resource can be found here:-
http://www.weatheronline.co.uk/cgi-bin/expertcharts?LANG=en&MENU=0000000000&CONT=soas&MODELL=gfs&MODELLTYP=1&BASE=-&VAR=pslv&HH=168&ARCHIV=0&PANEL=0&ZOOM=0&PERIOD=
It has a few different models available but [extreme caution] should be used when looking at models! In meteorology computer models can be used to predict things, computer models vary with their accuracy and most are [never completely right], especially on a “single run” but “ensembles” can be a very useful indicator, ensembles are created when they combine the last several runs into one median result. Another feature that is useful here too is located on the side panel “Parameter”(information available varies between models)different things like upper level winds and the like can be displayed and looking at the Zero hour picture conditions at the time can be assumed to be current.
Still on this site but about Fukushima,
http://www.weatheronline.co.uk/weather/news/fukushima
They are currently running a dedicated Fukushima page, it has an absolute multitude of information on it! It has models for dispersion (ZAMG,HYSPLIT,EURAD and FlEXPART), it contains links to TEPCO webcam, has Radiation doses for Tokyo and a list/map of testing stations, Current weather and also has in a little picture link at the bottom, the streamline winds earlier mentioned are right there at a click of a button as well as a satellite image link also. It also has further information located in the “More information” tab.
(Note: I am tragic at Meteorology, I can’t predict things well and I can’t read conditions much better but I am always open to questions, if I can’t answer them I may be able to take them to people who can answer them.)

(Note on JMA, they are just a recreation of the AMeDAS real time data)

(Note on wind statistics, the figures shown on maps indicate the sustained wind force NOT the absolute maximum gust, different met agencies use different sustain periods to separate winds and gusts, I am unsure on the duration JMA use, selecting a station can show both its wind and max gust)
