replies: text: I was in a dust devil myself years ago and it was weak. It could only lift dirt and grass and other plant life that was dead but I saw a rock and the rock didn't move so I just went in one. It was cool but dusty. 216.110.254.167 22:56, 27 April 2006 (UTC)
thread_title: Don't ...

message: There's some great movies of the Gusev Crater dust devils on this page. I replaced a so-so press-release link from JPL with this rather dedicated list, complete with several versions of most movies, a rating system based on stars, and a color photo! Some of them show multiple devils at the same time, but I don't have the technical expertise to replace the current one. Just a suggestion. Look and you'll see what I mean.--Planetary 01:04, 18 July 2006 (UTC)

Reference[13] "Characteristics of Dust Devils in Australia" http://adsabs.harvard.edu/abs/1990JApMe..29..498H.  and reference [14] http://concise.britannica.com/ebc/article-9076783/whirlwind It is known by glider pilots that the vortex of a willy-willy observed near ground level can occasionaly be 'felt' at heights up to about 15'000 feet.60.230.177.204 03:48, 20 January 2007 (UTC)

replies: text: Whirlwind is a generic term for the spectrum of whirls or vortices in the atmosphere, or in some usage specifically refers to a small whirl induced by strong winds interacting with a rough surface.  The article should be cleaned up or expanded to reflect this.  Evolauxia 04:22, 11 July 2007 (UTC)

thread_title:  merge 

message: Please, don't merge whirlwind with this article. Even though they are simular, they are very different! I know that they are simular phenominons, but a wirlwind is tecnicly a debris devil, since it:  
                     "picks up debris as it goes along on it's jurney"
                                                      -from whirlwind(atmospheric phenomenon) 
So please listen to me, don't merge Whirlwind (atmospheric phenomenon) with dust devil!!! 
                                
                                          Thanks! --Whirlwindlover 18:46, 16 July 2007 (UTC)

message: The "movie" showing the dust devil passing in front of one of the rovers: I thought I read somewhere that this was the first time a non-Earth weather event had been visualized from the surface - can anyone confirm? I think the same might apply to the satellite shots of the Martian dust devils, too. 68.146.81.123 (talk) 23:01, 13 June 2010 (UTC)
replies: text: "Weather event" is really a subjective term. Clouds and dust in the air had been imaged long before that sequence was taken. It's not really something that requires mention on the page, IMHO. -RunningOnBrains(talk) 22:14, 14 June 2010 (UTC)
thread_title: The Mars surface images - a first?

message: I live out here in the northern Arizona desert, I'm taking a college course in meteorology and have read the cause of whirl winds but some things do not make sense to me.  I have watched whirl winds start up in the same spot over and over again.  I have seen up to 16 starting at the same spot and travel the same course across the flat lands.  I realize the convection principle but why the same spot of origin?  —Preceding unsigned comment added by 173.87.187.183 (talk) 03:56, 8 September 2010 (UTC)

thread_title:  Dust devils do damage in Las Vegas, NV, on May 8, 2012 

message: The main article states that warmer air rises up through cooler air and that wind blows towards the bottom of the dust devil. Wind generally blows from high pressure to low pressure. Bouyancy of the hot air requires higher pressure underneath that air to apply the upwards force, but wind blowing towards the base seems to indicate lower pressure there. The article does mention hot air being stretched out vertically, though, which seems to explain this. The collumn of hot air reaches all the way down to the layer of heated air at the surface, so the heated air from the surface is rising as it expands, rather than the other way around. I mention this because the main article states that the warmer air loses it's bouyancy at some point. I wonder if the word bouyancy really applies at all. Air blowing across the surface towards the dust devil gains heat and therefore either pressure or volume. Outflow at the top of the dust devil increases pressure above the surrounding surface enough to keep the heated surface air from gaining volume. At the dust devil, that heated air gains volume as it expands upwards, so the bottom of the dust devil has higher pressure than the air above it, but less pressure than the surrounding surface air. Wind blows from high to low pressure. Fencelizard (talk) 14:23, 28 June 2016 (UTC)
