Abstract The robustness of the Numerical Atmospheric‐dispersion Modelling Environment (NAME) for forecasting dispersion volcanic ash clouds is investigated by comparing output from different Volcanic Ash Advisory Centre (VAAC) models initialised using parameters 2004 Grimsvötn, Iceland, eruption. London, Darwin, Washington, Montreal and Toulouse VAAC are all run operationally as if responding to Comparison model set‐ups reveals differing approaches between VAACs averaging times, release...
Weather forecasting is challenging because of the complex interplay between local conditions and regional atmospheric forcings. In this article, we analyse relationships daily rainfall large‐scale synoptic patterns in geographical context Réunion Island, a high volcanic island southwestern Indian Ocean basin. Given critical role trade winds on weather at scale, those across seasons defined with respect to yearly trade‐wind regimes. The analysis distribution inversion events' elevation...
The international research program “ReNovRisk-CYCLONE” (RNR-CYC, 2017–2021) directly involves 20 partners from 5 countries of the south-west Indian-Ocean. It aims at improving observation and modelling tropical cyclones in Indian Ocean, as well to foster regional cooperation improve public policies adapted present future risk this cyclonic basin. This paper describes structure main objectives ambitious project, with emphasis on its observing components, which allowed integrating numbers...
Seasonal tropical cyclone (TC) forecasting has evolved substantially since its commencement in the early 1980s. However, present operational seasonal TC services still do not meet requirements of society and stakeholders: current products are mainly basin-scale information, while more detailed sub-basin scale information such as potential risks landfall is anticipated for decision making. To fill this gap make science move forward, paper reviews recent research development forecasting. In...
The ReNovRisk-Cyclone program aimed at developing an observation network in the south-west Indian ocean (SWIO) close synergy with implementation of numerical tools to model and analyze impacts tropical cyclones (TC) present a context climate change. This paper addresses modeling part program. First, unique coupled system simulate TCs SWIO is developed. ocean–wave–atmosphere coupling considered along coherent between sea surface state, wind field, aerosol, microphysics, radiation. illustrated...
Climate change is a global challenge necessitating adaptation at the local level. Small island developing states (SIDS) in southwest Indian Ocean (SWIO) basin are particularly vulnerable and already facing significant challenges due to climate variability extreme weather events like tropical cyclones (TCs). Tailored services, catering their specific needs contexts, crucial for formulating appropriate strategies. This study aims fill gap of localized reliable information services SWIO region....

Under the responsibility of Regional Specialized Meteorological Centre (RSMC) La Réunion, southwest Indian Ocean (SWIO) has tropical cyclone activity close to that North Atlantic. Like most territories SWIO basin, Réunion island is highly vulnerable cyclone‐induced hazards and potential impact nearby storms closely related their track intensity evolution. Although storm forecasts have been steadily improving in last decades, a great amount uncertainty remains. Operational centres therefore...
Abstract Today, resilience in the face of cyclone risks has become a crucial issue for our societies. With climate change, risk strong cyclones occurring is expected to intensify significantly and impact way life many countries. To meet some associated challenges, interdisciplinary ReNovRisk programme aims study tropical their impacts on South-West Indian Ocean basin. This article presentation programme, which divided into four areas: cyclonic hazards, erosion solid transport processes,...
An accurate assessment of the amount solar radiation incident at specific locations is highly complex due to dependence available on many meteorological and topographic parameters. Reunion Island, a small tropical French territory, intends deploy energy technologies rapidly. In this context, variability intermittency irradiance in different regions island immediate interest if generated will be integrated existing network. This paper identifies features spatial temporal daily global...

Analysis of daily solar irradiation variability and predictability in space time is important for energy resources planning, development, management. The natural intermittency mainly triggered by atmospheric turbulent conditions, radiative transfer, optical properties cloud aerosol, moisture stability, orographic thermal forcing, which introduce additional complexity into the phenomenological records. To address this question data recorded during period 2011-2015, at 32 stations measuring...
Abstract We present a characterization of the variability clouds over southwest Indian Ocean between 2007 and 2010. Cloud occurrence is derived from DARDAR (raDAR/liDAR) mask, synergistic product based on Cloud–Aerosol Lidar Infrared Pathfinder Satellite Observation (CALIPSO) CloudSat measurements. It provides target classification for hydrometeors. demonstrate that this suitable studying vertical, spatial seasonal cloud distribution in Ocean. The increases approaching tropics: average...
Abstract Tropical volcanic islands are biodiversity hotspots where the Critical Zone (CZ) still remains poorly studied. In such steep topographic environments associated with extreme climatic events (cyclones), deployment and maintenance of monitoring equipment is highly challenging. While a few Observatories (CZOS) located in tropical regions, none them includes Montane Cloud Forest (TMCF) at watershed scale. We present here dataset first observatory from French network critical zone...
