Influence of water ice clouds on Martian tropical atmospheric temperatures by Wilson, R, Lewis, SR, Montabone, L, Smith, MD

“…We have identified a cold bias in the Control simulation of tropical temperature which develops in the northern hemisphere summer solstice season. We attribute this bias to the absence of radiatively active water ice clouds in the model and show that clouds likely play a prominent role in shaping the vertical thermal structure of the tropical atmosphere during this season. …”

The solsticial pause on Mars: 1. A planetary wave reanalysis by Lewis, S, Mulholland, D, Read, P, Montabone, L, Wilson, R, Smith, M

“…Transient waves are largest throughout the northern hemisphere autumn, winter and spring period and almost absent during the summer. …”

Seasonal reappearance of HCl in the atmosphere of Mars during the Mars year 35 dusty season by Olsen, KS, Trokhimovskiy, A, Montabone, L, Fedorova, AA, Luginin, M, Lefèvre, F, Korablev, OI, Montmessin, F, Forget, F, Millour, E, Baggio, L, Alday, J, Wilson, CF, Irwin, PGJ, Belyaev, DA, Patrakeev, A, Shakun, A

“…We also report two observations of > 2 ppbv HCl below 10 km in the northern hemisphere during the aphelion period.…”

Low-order dynamical behavior in the martian atmosphere: Diagnosis of general circulation model results by Martinez-Alvarado, O, Moroz, I, Read, P, Lewis, SR, Montabone, L

“…In this article we focus on a time series of the interval between autumn and winter in the northern hemisphere, when baroclinic activity is intense. …”

Polar vortices on Earth and Mars: A comparative study of the climatology and variability from reanalyses by Mitchell, D, Montabone, L, Thomson, S, Read, P

“…Unlike on Earth, it is found that the Martian polar vortices are annular, and that the Northern Hemisphere vortex is far stronger than its southern counterpart. …”

Assessing atmospheric predictability on Mars using numerical weather prediction and data assimilation by Rogberg, P, Read, P, Lewis, SR, Montabone, L

“…The intra-ensemble growth rates confirm earlier stand-alone model results, indicating that internal baroclinic transients lead to significant chaotic growth of model 'error' on time-scales of 3-10 sols only during NorthernHemisphere autumn and winter seasons. At other seasons, ensembles retain coherence at least over several tens of sols. …”

Investigation of air temperature on the nightside of Venus derived from VIRTIS-H on board Venus-Express by Migliorini, A, Grassi, D, Montabone, L, Lebonnois, S, Drossart, P, Piccioni, G

“…The present work extends the investigation of the average thermal fields in the northern hemisphere of Venus, by including the VIRTIS-H data. …”

Climatology and first-order composition estimates of mesospheric clouds from Mars Climate Sounder limb spectra by Sefton-Nash, E, Teanby, N, Montabone, L, Irwin, P, Hurley, J, Calcutt, S

“…They form in equatorial regions (30°S-30°N) during the aphelion season/northern hemisphere summer (Ls<150°), which is in agreement with previous published observations of mesospheric clouds. …”
