Cirrus and water vapor in the tropical tropopause layer observed by Upper Atmosphere Research Satellite (UARS) [PDF]

, 2003
The Microwave Limb Sounder (MLS) on Upper Atmosphere Research Satellite (UARS) is sensitive to water vapor and ozone in the lower stratosphere. The Cryogenic Limb Array Etalon Spectrometer (CLAES), another of the instruments on UARS, has a spatial and ...

Convective Rainfall in Amazonia and Adjacent Tropics

Atmospheric and Climate Sciences, 2015
Hourly rainfall estimates from integrated satellite data are used to build a dynamically based climatology of convectively generated rainfall across South America, including tropical, sub-tropical and oceanic regions. Herein, we focus on 0S to 15S, including greater Amazon and NE Brazil leeward of the South Atlantic Ocean.

Tropical ozone as an indicator of deep convection [PDF]

Journal of Geophysical Research: Atmospheres, 2002
The climatological ozone profile in the tropics is shaped like an “S,” with a minimum at the surface, a maximum at 330 K (∼6.5 km), another minimum at 345 K (∼11.2 km), and a subsequent increase toward the tropopause. These features can be reproduced by a very simple model whose only free parameter is the mean ozone mixing ratio of air detraining from ...

Three Generations of NARCliM: Evaluation of Precipitation, Temperature and Their Extremes Over the CORDEX Australasia Domain

International Journal of Climatology, EarlyView.
The NSW and Australian Regional Climate Modelling Version 2.0 (NARCliM2.0) builds on NARCliM1.0 and 1.5 to deliver improved regional climate simulations. This study provides the first comprehensive evaluation of NARCliM2.0 against its predecessors, assessing individual model skill in reproducing mean and extreme climate.

Relationship Between Deep Convection, Water Vapor, Lightning, and Precipitation over Northern Coastal Brazil

Atmosphere
A key component necessary to improve the performance of climate and weather forecasting models is understanding the physical mechanisms controlling tropical deep convection. In this study, the thermodynamic variables linked to deep convection within this

Interannual variability of the Tropical Atlantic independent of and associated with ENSO: Part II. The South Tropical Atlantic [PDF]

, 2006
Two dominant ocean-atmosphere modes of variability on interannual timescales were defined in Part I of this work, namely, the North Tropical Atlantic (NTA) and South Tropical Atlantic (STA) modes.

Simulation of the diurnal variation of the tropical convection

Acta Physica Sinica, 2009
The diurnal variation of the tropical convection is investigated using hourly outputs from a two-dimensional cloud-resolving model simulation. The features of cloud microphysics in tropical convections are proposed by the contrastive analysis of the simulation. The model is forced by the observational data obtained from tropical ocean global atmosphere

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, EarlyView.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Response of the West African Monsoon to the Madden–Julian Oscillation [PDF]

, 2009
Observations show that rainfall over West Africa is influenced by the Madden-Julian Oscillation (MJO). A number of mechanisms have been suggested: 1) forcing by equatorial waves; 2) enhanced monsoon moisture supply; and 3) increased African easterly wave

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?

International Journal of Climatology, EarlyView.
Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.
