AK47 0 #1 September 25, 2003 Hi, my name is AK and I have been skydiving once for my 21st b-day which was in march. I went with skydiving snohomish in WA. I am doing a speech presentation on skydiving and i am wondering what the temp differance from the ground to 10,000 feet. I am doing this tomorow, so i am hoping to get a response by 7:45am PST on the 25th. Thanks! -AK Quote Share this post Link to post Share on other sites

lazyfrog 0 #3 September 25, 2003 hi there, in dry atmosphere, consider a loss of temperature of 1C per 100m, humid atmosphere loss of 0.5C per 100m... depending on where you are and the weather can make a big difference... hope it helps you a bit. go back skydiving.---------- Fumer tue, péter pue ------------- ourson #10, Mosquito Uno, CBT 579 Quote Share this post Link to post Share on other sites
Amazon 7 #4 September 25, 2003 Hi AK... back in March in Snohomish it was COLD at altitude....when I did my first jump there on March 16th... the cieling was about 3500 ft.. and when I was on the strut of the Cessna.. i was being pelted with ICE pellets from the clouds just above... You can usually figure that the temp differences are about 3 degrees per thousand feet... That day it was about 45 degrees on the ground...take away 30 degrees for that and it would be about 15 degrees at altitude.. typically tho.. the airmass from off the Pacific is a bit warmer for the entire air mass/ air column... but it would still be below freezing up at 10,000 ft. When its really clear and cold though.. the 3 degree per thousand thing works fairly well. Who was your TM... Vladimir... Dr Death.....or Gui??
