Influence of convective transport on tropospheric ozone and its precursors in a chemistry-climate model [PDF]

, 2005
The impact of convection on tropospheric O3 and its precursors has been examined in a coupled chemistry-climate model. There are two ways that convection affects O3. First, convection affects O3 by vertical mixing of O3 itself.

The Convective Transport of Active Species in the Tropics (CONTRAST) Experiment [PDF]

Bulletin of the American Meteorological Society, 2017
Abstract The Convective Transport of Active Species in the Tropics (CONTRAST) experiment was conducted from Guam (13.5°N, 144.8°E) during January–February 2014. Using the NSF/NCAR Gulfstream V research aircraft, the experiment investigated the photochemical environment over the tropical western Pacific (TWP) warm pool, a region of ...

ResU‐Deep: Improving the Trigger Function of Deep Convection in Tropical Regions With Deep Learning

Journal of Advances in Modeling Earth Systems, 2023
Modeling deep convection accurately in tropical regions is important. However, biases remain in current trigger functions. To alleviate the overestimation of frequency and wrong depiction of the diurnal cycle, we propose a deep convection trigger ...

Downdraft impacts on tropical convection

, 2013
Downdrafts are an integral part of the convective cycle, and have been observed and documented for more than a hundred years. But many questions still surround convective downdrafts and their most difficult to observe properties. These questions have made the parameterization of convective downdrafts in global climate models (GCMs) very difficult ...

Recent Studies on Changes in Track and Convection Associated with Tropical Cyclone Landfall

Tropical Cyclone Research and Review, 2012
: As a tropical cyclone makes landfall, changes in friction and moisture as well as the presence of topography will modify the flow and subsequently the convection associated with the tropical cyclone. As a result, the distribution of potential vorticity

How important is tropospheric humidity for coastal rainfall in the tropics?

Geophysical Research Letters, 2016
Climate models show considerable rainfall biases in coastal tropical areas, where approximately 33% of the overall rainfall received is associated with coastal land‐sea interaction.

Relating tropical ocean clouds to moist processes using water vapor isotope measurements [PDF]

Atmospheric Chemistry and Physics, 2011
We examine the co-variations of tropospheric water vapor, its isotopic composition and cloud types and relate these distributions to tropospheric mixing and distillation models using satellite observations from the Aura Tropospheric Emission Spectrometer

The effect of deep, tropical convection on the tropical tropopause layer [PDF]

Journal of Geophysical Research: Atmospheres, 2002
There is evidence that most detrainment from tropical convection occurs below ∼14 km, about 2 km below the tropopause. On the other hand, it is also generally accepted that convection does occasionally reach the altitude of the tropopause. The question is whether the relatively infrequent penetrations above 14 km are sufficient to influence the ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
