Jim Koermer invited me to come up today and “work” a session with him. Jim is a Professor of Meteorology at Plymouth State in Plymouth, New Hampshire. During NEAQS he is responsible for providing the scientist on the BROWN twice daily forecast of the weather conditions. Yesterday evening I drove the 2 hours to Plymouth and went to Jim’s house. After a short visit with Jim and his wife it was about 9:00 PM. It was time for a nap, only a nap because his work session today started at midnight.
One of Jim’s students had worked the previous session. After we arrived he gave Jim a brief summary of what he had been doing. Rachel, another of Jim’s students soon joined us and she went to work immediately gathering some of the data necessary to make the forecast.
Along one wall of the long room, where they build the forecast, is a bank of 34 displays each continually updating satellite images, radars, computer models, webcams and other global and local weather information. On the desk are four computers which are used to gather other weather data and computer models which give real time, delayed time and computer models which predict general weather patterns.
Rachel and Jim are writing a very specific forecast for the area of the Gulf of Maine in the location of the BROWN. Their predictions give details such as wind speed and direction, air temperature, rainfall, cloud cover and where pollution will be starting from and then will move to. Even though they send the BROWN these predictions twice a day the forecast are for the next 48 hours, at six hour intervals. Until 6:00AM the two of them analyze the information from all of the different sources and then they hand draw some of the predictions on maps and type the rest. The drawn maps are scanned and merged with the typed predictions and the entire file is loaded to a website for the BROWN to access when it connects to the web by satellite at 7:00. You can see one of the hand drawn predictions in one of the pictures I sent in earlier from the BROWN.
The scientists on the BROWN will then use the predictions to determine what will be the best place for them to sample pollution. The BROWN does not travel very fast so plans have to be made ahead of time to catch certain pollution events.
You can also use a lot of the tools that Jim uses. His website is at http://vortex.plymouth.edu/
