Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from Earth with help from a telescope.
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
During the winter season on Mars, temperatures at the planet’s polar caps can reach below CO 2 ’s condensation temperature (150 K). Noted as orbit #10075 by Dr. Ivanov and Dr. Muheleman of the Mars Global Surveyor, data from the MOLA instrument recorded cloud returns at the planet’s south polar cap during the southern winter season.

The "polar vortex" that plunged Canada and the U.S. into historical cold last winter is said by researchers to have occurred because melting polar ice changes weather patterns, according to a ...
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather. Cold subsides when the ...
First day of winter is here: Snow and cold in forecast as winter begins The West: Rain and warm temperatures. Rain along the West Coast over Saturday and Sunday will douse northern California, the ...
This is a list of television programs broadcast by the American television network The Weather Channel. There are four main types of programs on The Weather Channel: weather news programs, serial documentaries, Long-form shows, and specials such as the 100 Biggest Weather Moments , Top 100 Weather Moments , and Coast Guard: HMS Bounty .
Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.
