The Atmospheric Dynamics of Venus [PDF]

Space Science Reviews, 2017
We review our current knowledge of the atmospheric dynamics of Venus prior to the Akatsuki mission, in the altitude range from the surface to approximately the cloud tops located at about 100 km altitude. The three-dimensional structure of the wind field in this region has been determined with a variety of techniques over a broad range of spatial and ...

Dynamics of Jupiter’s Atmosphere [PDF]

Highlights of Astronomy, 1998
AbstractResults from the Galileo probe and orbiter are compared with Voyager and ground-based results. The probe made measurements to the 20-bar level, well below the nominal cloud base at 5 bars and well below the level where sunlight is absorbed. The winds increased with depth within the clouds and then remained constant below cloud base.

Sensitivity of nitrate aerosols to ammonia emissions and to nitrate chemistry: implications for present and future nitrate optical depth [PDF]

Atmospheric Chemistry and Physics, 2016
We update and evaluate the treatment of nitrate aerosols in the Geophysical Fluid Dynamics Laboratory (GFDL) atmospheric model (AM3). Accounting for the radiative effects of nitrate aerosols generally improves the simulated aerosol optical depth ...

Limited surface impacts of the January 2021 sudden stratospheric warming

Nature Communications, 2022
Subseasonal weather prediction can reduce economic disruption and loss of life, especially during “windows of opportunity” when noteworthy events in the Earth system are followed by characteristic weather patterns.

Volcanic Drivers of Stratospheric Sulfur in GFDL ESM4

Journal of Advances in Modeling Earth Systems, 2023
Stratospheric injections of sulfur dioxide from major volcanic eruptions perturb the Earth's global radiative balance and dominate variability in stratospheric sulfur loading.

A new airborne laser-induced fluorescence instrument for in situ detection of formaldehyde throughout the troposphere and lower stratosphere [PDF]

Atmospheric Measurement Techniques, 2015
The NASA In Situ Airborne Formaldehyde (ISAF) instrument is a high-performance laser-based detector for gas-phase formaldehyde (HCHO). ISAF uses rotational-state specific laser excitation at 353 nm for laser-induced fluorescence (LIF) detection of HCHO ...

Observationally constrained projection of Afro-Asian monsoon precipitation

Nature Communications, 2022
A new study shows the latest climate models tend to overestimate future Afro-Asian monsoon rainfall and runoff due to present-day biases of warming patterns. By constraining biases, the rainfall increase is 70% of the raw projection.

Ocean Ammonia Outgassing: Modulation by CO2 and Anthropogenic Nitrogen Deposition

Journal of Advances in Modeling Earth Systems, 2020
The imprint of anthropogenic activities on the marine nitrogen (N) cycle remains challenging to represent in global models, in part because of uncertainties regarding the source of marine N to the atmosphere.

Increased impact of heat domes on 2021-like heat extremes in North America under global warming

Nature Communications, 2023
The heat dome explains about 55% of the 2021 Western North American high temperatures. The intensity of heat extremes associated with such circulations are increasing faster than background global warming due to soil moisture feedbacks.

Effects of latitude-dependent gravity wave source variations on the middle and upper atmosphere [PDF]

Front. Astron. Space Sci., 2020, 2020
Atmospheric gravity waves (GWs) are generated in the lower atmosphere by various weather phenomena. They propagate upward, carry energy and momentum to higher altitudes, and appreciably influence the general circulation upon depositing them in the middle and upper atmosphere.
