Comment Forecasting practices (Score 5, Informative) 235

Most forecasting is done by meteorologists viewing the predicted conditions based on a numerical model that normally gets run every 12 hours. The model's forecast is usually pretty good out to 72 hours or so. What happens is that an experienced weather-guesser (ex-Navy, here) will look at the model's output (which lags realtime to some degree) and compare the prediction to the actual conditions for the timeframe in question. If the correlation is high, he/she will put more faith into the model's longer term predictions. If the model isn't tracking reality very well, the forecaster will rely on experience rather than the numerical prediction for the longer-range forecast.

Sounder data from the available weather satellites is used to seed the modelling software as close to its run time as possible, to set up starting conditions for the observable areas. If that data is lacking, the previous model run data closest to the time of the new run is used. (GIGO applies...)

The realtime data can also come from radiosondes, official observations stations, buoys, or what have you. Losing a bird doesn't mean the forecasting infrastructure will fall apart; it just means that imagery will come from a different source (= different angle, with attendant distortion), and some loss of realtime input for the model run.

Tomorrow's Science Heroes? 799

An anonymous reader writes "As a kid I was (and still am) heavily influenced by Carl Sagan, and a little later by Stephen Hawking. Now as I have started a family with two kids, currently age 5 and 2, I am wondering who out there is popularizing science. Currently, my wife and I can get the kids excited about the world around them, but I'd like to find someone inspiring from outside the family as they get older. Sure, we'll always have 'Cosmos,' but are there any contemporaries who are trying to bring science into the public view in such a fun and intriguing way? Someone the kids can look up to and be inspired by? Where is the next Science Hero?"

Comment Font color selection (Score 1) 702

When looking for a fg/bg color combination, I will use whatever color choosing applet I have available that provides a color wheel and choose two colors that are diametrically opposed. It works well in almost all cases, and though some of the combos are butt-ugly, they all tend to be quite legible...
