HDOB Recon Plot for date range

#1 Postby AGM » Thu Aug 30, 2012 12:11 am

I have been looking at the HDOB recon data and trying a few plots.
The recon list is from.
http://www.nhc.noaa.gov/archive/recon/2012/AHONT1/
I just use the files for one day for testing.
The hurricane satellite image is from here.
http://weather.msfc.nasa.gov/cgi-bin/get-goes?satellite=GOES-E%20HURRICANE&&lat=28&lon=-90&quality=100&width=800&height=800&zoom=1
The image location lat lon is taken from the HDOB reports. As the program scans through the data it saves the most north west location.
The image is being put together using imagemagick. The dot colors are wind speed, using common map wind speed colors. All the recons for the day are plotted below the storm center. I did this so the plot data could be seen as well as the storm center at the same time.
If anyone has any ideas or feedback I would be interested in it., Thanks John

Welcome to S2K! As far as feedback, what is it your trying to accomplish with this? You wrote, "I did this so the plot data could be seen as well as the storm center at the same time." - Isn't this already done by imagery from Google Earth that's regularly posted here? I don't have it installed but I think you can do different overlays including the current NHC position.

EDIT: I see the images now, but I'm still confused at what this is trying to illustrate.

Cyclenall, Thanks for your interest. This does not use google tools. Why?, Weather is interesting, so having a look at what can be done with public data.
Image
This one has wind direction symbols, wind speed and pressure. The pressure is displayed as the two soft colors using a selection switch of eye forming millibars.
Working now to plot the symbols by color intensity like a painting is made. This way the higher contrast symbols will be plotted last so they are not lost. Next I will be looking at adding in drop data and sea buoys. Note- the sat image is from today and the HDOB data is from 2012-08-28
Image
This one is the same as the one above, but with the significant data plotted on the top. Also the higher pressures and low wind plots were skipped. It gives a pretty good snapshot of what the storm is doing I think.

Image
This is with the HDOB on the bottom against black for easy reading. The top sat view is zoomed out for a wider view. This leaves room for plotting ship data, wave heights, drop data or any other information that might be available. Maybe the short position and storm status somewhere at the side.
Image
This is with some buoy data plotted in. My thought is to only display major wave height by color code and wind direction by the symbol point. Maybe display buoys within a few hundred miles of the storm.

Here is a good tutorial for those who dont know a lot about how to follow the recon data. There are new things that NHC has added for the 2013 season.
