A planetary-scale streak structure in the Venusian lower-cloud layer was observed by the Akatsuki orbiter. Here the authors present numerical simulations that reproduce such structure and reveal that a low-stability layer, which induces baroclinic di

Publikováno v: Journal of geophysical research atmospheres. 126(11):e2019

Ishiwatari et al. (2007) (https://doi.org/10.1029/2006JD007368) investigated multiple equilibrium solutions of a gray atmosphere for various values of solar constant, utilizing two types of models, namely, a one-dimensional energy balance model and a

The circulation pattern and day-night heat transport in the atmosphere of a synchronously rotating aquaplanet: Dependence on planetary rotation rate

Autor: Masaki Ishiwatari, Masanori Onishi, Shin-ichi Takehiro, Yoshiyuki O. Takahashi, Satoshi Noda, Kensuke Nakajima, George Hashimoto, Kiyoshi Kuramoto, Yoshi-Yuki Hayashi

Publikováno v: Icarus. 282:1-18

In order to investigate a possible variety of atmospheric states realized on a synchronously rotating aquaplanet, an experiment studying the impact of planetary rotation rate is performed using an atmospheric general circulation model (GCM) with simp

A Numerical Study of Convection in a Condensing CO2 Atmosphere under Early Mars-Like Conditions

Autor: Kensuke Nakajima, Yoshiyuki O. Takahashi, Masaki Ishiwatari, Tatsuya Yamashita, Yoshi-Yuki Hayashi, Seiya Nishizawa, Ko ichiro Sugiyama, Masatsugu Odaka

Publikováno v: Journal of the Atmospheric Sciences. 73:4151-4169

Cloud convection of a CO2 atmosphere where the major constituent condenses is numerically investigated under a setup idealizing a possible warm atmosphere of early Mars, utilizing a two-dimensional cloud-resolving model forced by a fixed cooling prof

Martian dust devil statistics from high-resolution large-eddy simulations

Autor: Seiya Nishizawa, Hisashi Yashiro, Hirofumi Tomita, Ko-ichiro Sugiyama, Shin-ichi Takehiro, Masatsugu Odaka, Yoshiyuki O. Takahashi, Yoshi-Yuki Hayashi, Yousuke Sato, Masaki Ishiwatari, Kensuke Nakajima

Publikováno v: Geophysical Research Letters. 43:4180-4188

Dust devils are one of the key elements in the Martian atmospheric circulation. In order to examine their statistics, we conducted high-resolution (up to 5 m) and wide-domain (about 20 × 20 km2) large-eddy simulations of the Martian daytime convecti

The Aqua-Planet Experiment (APE): Response to Changed Meridional SST Profile

Publikováno v: Journal of the Meteorological Society of Japan. Ser. II. :57-89

This paper explores the sensitivity of Atmospheric General Circulation Model (AGCM) simulations to changes in the meridional distribution of sea surface temperature (SST). The simulations are for an aqua-planet, a water covered Earth with no land, or
