I am starting a new plugin to display long term weather
Sort of like the wind
atlas. There will be many modes of display, but the basic one has wind
barbs in the 8 directions with lengths relative to the percentage of time, and barbs showing strength. Then in the center is either in red, the percentage of time over 40 knots, or else, in blue the percentage of time under 5 knots whichever is more.
There will also be a displays showing all the past tropical storm tracks, and typical ITCZ position. Then a list to select which month of the year, or all months. It may be helpful to have a box to select el nino/la nina or both
Next it might be possible to show relevant ocean currents sea temperatures, rainfall patterns, and possibly swell. Am I forgetting anything?
Now for the critical bit.. does anyone know where I can get the data I need? Should I just download as many gribs as I possibly can and generate it from that? Please post as many sources for possible data so I can implement this.
