Venus ’s unusually thick atmosphere is typically regarded as a barrier that prevents us from gazing upon its torture surface . By study subtle shifts in weather condition traffic pattern , however , scientist have get wind that these swarm also offer significant clues as to what lies beneath .
young researchpublishedin the Journal of Geophysical Research shows there ’s another way of life to study the topography of this mysterious major planet , and that ’s by expect at the very matter that ’s blur its surface : cloud . Using radar and infrared lighting , the researcher do to thrust our nearest worldwide neighbor ’s oppressive atmosphere and compeer below .
Like Earth , Venus features muckle range , canyons , break valleys , and Brobdingnagian plains . And like our planet , these Earth’s surface features influence weather . Weather is markedly different on Venus than it is on Earth , and scientists are now starting to get a handle on just how uncanny it is .

owe to a greenhouse effect , the surface of Venus is a singe 450 stage Celsius . Ground - level winds are achingly dull , moving at just three invertebrate foot a second . But things are different higher up , where winds strain up of 30 to 45 geographical mile per hr , and where temperature reach a more manageable and Earth - comparable -70 degrees Celsius ( -94 degrees Fahrenheit ) . Even higher up , near the top of the 12 - mile - chummy atmospheric layer , the winds ball up hundreds of prison term quicker than they do on the Earth’s surface .
Using the Venus Express Satellite , an international team of astronomer , including a team from the Max Planck Institute in Germany , analyze three unlike aspects of the major planet ’s cloudy atmospheric condition , namely the speeds at which these cloud disperse , the amount of water locked up in these clouds , and the luminance of these swarm across the optical spectrum ( particularly in ultraviolet Light Within ) . Together , these three aspects could be connected to surface features below .
For deterrent example , the researchers discovered one particular sphere of swarm near the equator that contained more water vapor than usual . It just so happens that this “ damp ” region is located directly above a 15,000 - infantry - high mountain range called Aphrodite Terra . water supply - ample tune from the low ambiance is being forced upwards above the mountains , get the unusually wet cloud . The researchers knight this meteorological feature article , the “ Fountain of Aphrodite . ”
To explicate this effect , the researchers point to a phenomenon sleep together as gravity waves , which should n’t be confused with gravitational waves . ( Those are very unlike ) .
“ Gravity wave are an atmospheric phenomenon we often see in cragged parts of Earth ’s surface , ” explain Jean - Loup Bertaux of LATMOS ( Laboratoire Atmosphères , Milieux , Observations Spatiales ) , and lead generator of the novel study , in a statement . “ Crudely speaking , they form when air babble over jolting surface . The wave then spread vertically upwards , grow larger and enceinte in bounty until they break just below the swarm - top , like ocean waves on a shoreline . ”
As the waves break , they promote back against the fast - moving high - ALT winds which slow them down . This results in a fart circulation system that functions like an breeze heart ; body of water - rich air is thrown up into the atmosphere , create the “ fountain ” and a result downwind feather of vapor . standardised effects were maintain along other craggy regions along Venus ’s equator , where the warmer temperature fire this special weather feature .
This research is of import — and not just because it improve our reason of Venus . The fresh detail also raise our intellect of clime as well . Our planet is steady warming due to the unfluctuating release of greenhouse flatulency , so it would behoove us to learn as much about this stifling hot planet as possible .
