ChasingBlueSky 0 #28 September 8, 2005 Quote They are caused by turbulent air, here on the front range the mountains help cause the turbulence so tornadoes don't normally form here, but go east far enough from the mountains and it's the thunderhead that creates the turbulence. That is when seeing them is a bad omen, in ND we would just go strait in the basement when you would see those and they were green. I can't think of once where the tornado sirens didn't blow soon after. Around here they are good sign that bad weather is here and you should take shelter. I would say 9/10 times I've seen them, there has been a tornado siren going off. Other things that tend to happen is odd color changes, often green, and major temp drops in a very short period of time._________________________________________ you can burn the land and boil the sea, but you can't take the sky from me....

Other things that tend to happen is odd color changes, often green, and major temp drops in a very short period of time. From the previously linked website. The method by which they are formed would seem conducive to a drop in temperature and possibly a color change as well (subsiding cooler air containing larger water particles) QuoteAs updrafts carry precipitation enriched air to the cloud top, upward momentum is lost and the air begins to spread out horizontally, becoming a part of the anvil cloud. Because of its high concentration of precipitation particles (ice crystals and water droplets), the saturated air is heavier than the surrounding air and sinks back towards the earth. The temperature of the subsiding air increases as it descends. However, since heat energy is required to melt and evaporate the precipitation particles contained within the sinking air, the warming produced by the sinking motion is quickly used up in the evaporation of precipitation particles. If more energy is required for evaporation than is generated by the subsidence, the sinking air will be cooler than its surroundings and will continue to sink downward.

bmcd308 0 #30 September 8, 2005 Those formed over WTS on day, and Mike Mullins, who knows lots about the weather, pointed them out and called them exactly that, indicating that they were a sign of tornadic activity and at least severe thunderstorms. He also said that we did not want to be skydiving near them, nor did he want to be flying near them. ---------------------------------- www.jumpelvis.com Quote Share this post Link to post Share on other sites
Hooknswoop 19 #31 September 8, 2005 I see them often here in CO. Definately a sign of bad weather. Derek Quote Share this post Link to post Share on other sites
