intelligent barograph

Are there barographs available which plot the first derivative of the pressure with respect to time, and would such a plot be useful alongside the pressure signal itself? I have developed a barograph which is is capable of such things, but I wonder what the most useful printout might be. The current state of the art is visible at http://www.meteormetrics.com and I would welcome comment, especially if there is a useful parameter I could calculate and include on future versions. Thanks Kevin Scott I would argue that it would be very useful... if the information could be distributed to the forecasters as part of the site's observation. It should permit better automated analysis of frontal passages (trough passage), Low deepenings/weakenings, etc.... stuff much of which is either done manually or by software kludges interpolating from the hourly MSLP values. As long as the primary curve is suitable smoothed (running time-average over several minutes, perhaps??) before the derivative is taken. By the way... what is the pressure-sensing technology on that device? It surprises me that it would not be considered accurate to a tenth of mb, given all the temperature compensation, etc. ??? -- God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. --- Serenity Prayer |
