   It is called Thermals and can do a lot of work. Just ask a glider pilot!

   …..It’s why you don’t load your aircraft to the same capacity on a blistering hot day as on a cold day.

     Also why you need longer runways in the desert!
     That is why the weather service measures temperatures at airports. It has nothing to do with “Climate” but to give pilots an idea about current and expected flying conditions. That is probably why the NOAA is part of the department of Commerce.

   In Meteorology 101, we learned about diurnal variations of barometric pressure.

   From a 2006 RSC-approved mainstream scientific opinion piece:

   will the Venus Express mission really contribute to our understanding of Earth’s greenhouse effect as some press reports would have us believe? It seems unlikely. The two planets are just too different now. Perhaps if the Venus Express probe had been launched when Venus was beginning to lose her water (about four billion years ago) the results would have been revealing. This highlights an important point about studying climate change on this, or indeed any, planet. For it to be truly useful somehow we must grasp a historical perspective of what happened and when. Only then can we hope to arrive at the how and why.

   Understanding Venus’ greenhouse effect will probably have to wait until we have made real progress in unravelling its geological history…
