Let&#39;s say a good pace will gain you 2000ft of elevation every three hours, that&#39;s a pressure drop of 2 inches Hg. I&#39;m not a meterologist, but after reading up a bit, my understanding is that a strong storm might give an average pressure drop of ONLY 0.1-0.2 in Hg over 3 HOURS. Only in hurricanes or other rare weather events will pressure drops even approach 0.5-1 in Hg over three hours. If this is correct, then how could the storm alarm function on an ascent? I sersiouly doubt that it can, nor was it intended to do so. question_37340 Mon, 17 Nov 2008 10:27:12 GMT http://www.backcountry.com/outdoorgear/Brunton-Atmospheric-Data-Center-Summit/BRU0050M.html?CMP_ID=QRSS_29578#question_29578 Brunton Atmospheric Data Center Summit<br /><br />Barometers only function properly when your altitude isn&#39;t changing, thus, how could the storm alarm function when you&#39;re ascending a peak? I suspect that this product description might be a bit misleading - the storm alarm should work nicely when you&#39;re at camp for some time, but not while climbing (a GPS/barometer, however, could be capable of this as it can determine your altitude independent of air pressure). question_29578 Tue, 28 Oct 2008 09:00:42 GMT http://www.backcountry.com/outdoorgear/Brunton-Atmospheric-Data-Center-Summit/BRU0050M.html?CMP_ID=QRSS_5058#question_5058 Brunton Atmospheric Data Center Summit<br /><br />What type of battery does this use? How long does the battery last? Can it be used with a solar recharger? question_5058 Mon, 28 Apr 2008 08:59:34 GMT
