The Venus' Cloud Discontinuity in 2022
J. Peralta, A. Cidadão, L. Morrone +10
First identified in 2016 by JAXA's Akatsuki mission, the discontinuity/disruption is a recurrent wave observed to propagate during decades at the deeper clouds of Venus (47--56 km…
A Long-lived Sharp Disruption on the Lower Clouds of Venus
J. Peralta, T. Navarro, C. W. Vun +19
Planetary-scale waves are thought to play a role in powering the yet-unexplained atmospheric superrotation of Venus. Puzzlingly, while Kelvin, Rossby and stationary waves manifest…
Planetary-scale variations in winds and UV brightness at the Venusian cloud top: Periodicity and temporal evolution
Masataka Imai, Toru Kouyama, Yukihiro Takahashi +9
Planetary-scale waves at the Venusian cloud-top cause periodic variations in both winds and ultraviolet (UV) brightness. While the wave candidates are the 4-day Kelvin wave and 5-d…
Long-term variations of Venus' 365-nm albedo observed by Venus Express, Akatsuki, MESSENGER, and Hubble Space Telescope
Yeon Joo Lee, Kandis-Lea Jessup, Santiago Perez-Hoyos +16
An unknown absorber near the cloud top level of Venus generates a broad absorption feature from the ultraviolet (UV) to visible, peaking around 360 nm, and therefore plays a critic…
New cloud morphologies discovered on the Venus's night during Akatsuki
J. Peralta, A. Sánchez-Lavega, T. Horinouchi +8
During the years 2016 to 2018, the instruments Akatsuki/IR2 (JAXA) and IRTF/SpeX (NASA) acquired a large set of images at 1.74, 2.26 and 2.32 μm to study the nightside mid-to-lower…
Global structure of thermal tides in the upper cloud layer of Venus revealed by LIR onboard Akatsuki
T. Kouyama, M. Taguchi, T. Fukuhara +11
Longwave Infrared Camera (LIR) onboard Akatsuki first revealed the global structure of the thermal tides in the upper cloud layer of Venus. The data were acquired over three Venusi…
Equatorial jet in the lower to middle cloud layer of Venus revealed by Akatsuki
T. Horinouchi, S. Murakami, T. Satoh +15
The Venusian atmosphere is in a state of superrotation where prevailing westward winds move much faster than the planet's rotation. Venus is covered with thick clouds that extend f…
Venus cloud morphology and motions from ground-based images at the time of the Akatsuki orbit insertion
A. Sánchez-Lavega, J. Peralta, J. M. Gómez-Forrellad +7
We report Venus image observations around the two maximum elongations of the planet at June and October 2015. From these images we describe the global atmospheric dynamics and clou…
