OceanStWx Posted September 4, 2013 Share Posted September 4, 2013 Is storm data the same as the summary from NCDC storm events database? It is, except that the storm events database does not go back as far as Storm Data. Link to comment Share on other sites More sharing options...
CT Rain Posted September 4, 2013 Share Posted September 4, 2013 Is storm data the same as the summary from NCDC storm events database? Should be, yeah. You can go back to the 1950s here... just search by month. http://www.ncdc.noaa.gov/IPS/sd/sd.html Link to comment Share on other sites More sharing options...

Ginx snewx Posted September 4, 2013 Share Posted September 4, 2013 THE FOLLOWING CHART DEPICTS THE FREEFALL VELOCITY AND FREEFALL ENERGY ASSOCIATED WITH FALLING HAILSTONES. KEEP IN MIND THAT SOME HAILSTONES WILL FALL AT DIFFERENT SPEEDS DUE TO THEIR SHAPE, DENSITY, SPIN AXIS, COLLISIONS WITH OTHER STONES, ETC. HAIL SIZE (IN) FREEFALL VELOCITY (MPH) FREEFALL ENERGY (FT-LBS) 0.50 34.7 .009 0.75 42.3 .044 1.00 49.8 1.43 1.25 55.9 3.53 1.50 61.4 7.35 1.75 66.2 13.56 2.00 71.6 23.71 THIS MEANS THAT A 2-INCH HAILSTONE PACKS NEARLY 17 TIMES THE PUNCH OF A 1-INCH HAILSTONE. . MANY ROOFING AND SIDING PRODUCTS AS WELL AS VEHICLE METAL ARE DENTED BY HAIL, ESPECIALLY BEGINNING IN THE 1.0 TO 1.5 INCH DIAMETER RANGE. Link to comment Share on other sites More sharing options...

This is what drove the change in severe criteria from 0.75" to 1.0". Good times dodging baseball size hail that is moving nearly 100 mph. Link to comment Share on other sites More sharing options...

Most of the hail damage in this country is to dealerships, hail has a way of finding the Acura, Mercedes ones for some reason, lol Link to comment Share on other sites More sharing options...
