A regional dust storm was observed in the northern spring of Martian Year 35, a period characterized by relatively cold and clear atmosphere. Satellite observations general circulation model simulations indicate that atmospheric temperature response to this early closely resembles an equatorial counterpart responses typically during high loading season.

This study investigated high-frequency gravity waves (HFGWs) observed by the Zhurong/Tianwen-1 and Perseverance/Mars 2020 rovers between 09:00 11:00 local time, from Ls 140° to 165° in Mars Year 36. By analyzing eccentricity of hodographs for monochromatic wind perturbations obtained horizontal perturbation, HFGWs were identified via their predominantly linear characteristics.The propagation directions these determined using polarization relationships theory HFGWs.

Growing evidence supports the existence of subsurface water ice on Mars, though direct groundwater remains scarce. Using seismic data from seasonal marsquakes, we provide compelling for within approximately 2 meters surface, restricted to localized regions in northern mid-latitudes. The observed rapid variability marsquake activity suggests that changes pore pressure, driven by melting during warmer seasons, play a critical role triggering these events. This mechanism explains key...
Dust and water vapor are key components influencing radiative processes in the Martian atmosphere. We identify a distinct barrier mechanism driven by planetary-scale Hadley circulation (HC), which plays significant role controlling global spatial distribution of dust vapor. Using six years output data from Ensemble Mars Atmosphere Reanalysis System (EMARS), we analyze behavior these during northern winter. Our results reveal contrasting patterns: is predominantly confined within HC, while...

Abstract Multilanders and rovers on Mars have observed the diurnal variation in surface pressure with two significant peaks at dawn twilight (around 8:00 a.m. p.m.) different locations near equinox. The Dynamic Meteorology Laboratory Martian General Circulation Model (GCM) simulates similar phase‐locked fluctuations. a certain local time occur most mid‐ low‐latitude locations, as GCM simulations suggested. By reconstructing from horizontal mass flux obtained simulations, we find that...
Abstract The seasonal variations in gravity wave (GW) vertical fluxes of zonal momentum and heat the mesopause region are calculated using nearly 10 years (from 2012 to 2021) temperature wind observations by a narrowband sodium lidar located Hefei, China (32°N, 117°E). Except summer, GW mostly westward, with ∼80% contributed short‐period (10 min–1 hr) GWs, anticorrelate eastward wind. mean westward spring winter −2.55 −1.78 m 2 /s , respectively, which much stronger than −0.98 fall. flux...
During the northern spring (approximately Ls≈33°) in Martian Year 35, Mars experienced an unusual dust storm characterized by significantly increased troposphere. As observed Climate Sounder (MCS), temperature increases mid-latitude troposphere of both hemispheres and decreases mesosphere during event. The response simulated General Circulation Model (GCM) agrees with MCS observations. radiative heating from is responsible for In contrast, dynamic heating/cooling contributes to variations...
