We have been looking close at the cloud of Venus for almost 55 years ,   and we have finally now found a room to use them to study about what lies beneath .

European scientist used data from ESA ’s Venus Express spacecraft , which was de - revolve in 2015 , and discovered a link between the Venusian conditions radiation diagram and what the control surface below looks like .

In a paper , published in theJournal of Geophysical Research : Planets , the investigator discourse the wind stop number and water subject in the clouds above Aphrodite Terra , a 4,500 - m - high ( 2.8 - geographical mile - eminent ) succor on the equator that ’s just about the size of Africa . The squad thinks that the height of the neighborhood is creditworthy for the different weather .

" Our results exhibit that all of these view – the wind , the water cognitive content , and the cloud composition – are somehow link up to the properties of Venus ' surface itself , " said tip writer Jean - Loup Bertaux in astatement .   " We used reflexion from Venus Express span a period of six years , from 2006 to 2012 , which allowed us to study the planet ’s long - terminus weather patterns . "

While Venus is too hot and teetotal for liquid water supply , water vapor is present in the air . Bertaux and his confrere used an infrared demodulator to estimate the amount of water present around the planet and they give away a especially " damp " region just above the equator .

At the same time , the squad also looked   at the wind speed and strike that the winds near the damp smirch were about 18 percent slower than in environ region . This area   seemed way of life too special .

They seem at how the winds and water supply might be connected to the high ALT of Aphrodite Terra , and pick up that large waves in the atmosphere crash on the relief like sea wave on a   shore , slowing down the high - ALT winds and helping press up the water vapor from the lower standard atmosphere .

" This certainly challenges our current General Circulation Models , " said   Håkan Svedhem , ESA Project Scientist forVenus Express , in the argument .   " While our good example do acknowledge a connection between topography and climate , they do n’t usually produce dour conditions patterns connected to topographic open features . This is the first time that this link has been shown clearly on Venus – it ’s a major result . "
