Martian atmosphere churns harder in south making north wetter.
Mars: height variations lead to a wet north pole.
The changing face of the northern polar ice cap.
Scientists have figured out why its wet up north - on Mars. A new computer simulation of the martian atmosphere suggests that the planets geography causes differences in atmospheric circulation within the northern and southern hemispheres. These differences dump more water on the martian north pole, where it adds to the seasonal ice-cap.
Mark Richardson of the California Institute of Technology in Pasadena and John Wilson of the Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey, find that the thin martian air, which is mostly carbon dioxide, rises and falls more vigorously in the southern than in the northern hemisphere1.

A stellar flare 10 times more powerful than anything seen on our sun has burst from an ultracool star almost the same size as Jupiter
A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
