Abstract. A large number of intense cyclones occur every year in the Mediterranean basin, one climate change hotspots. Producing a broad range severe socio-economic and environmental impacts such densely populated region, call for coordinated interdisciplinary research efforts. This article aims at supporting these efforts by reviewing status knowledge field cyclones. First, we focus on climato...

issues of science and politics. Because of their significant and visceral impacts, discussion of extreme events is a frequent locus of such conflation. Linda Mearns, of the National Center for Atmospheric Research (NCAR), aptly characterizes this context: “There’s a push on climatologists to say something about extremes, because they are so important. But that can be very dangerous if we really...

Tropical cyclones and storms, hurricanes, powerful thunderclouds, which generate tornadoes, destructive ex-tratropical cyclones, which result in catastrophic floods, are the powerful cloud systems that contain huge amount of water. According to the hypothesis argued in this paper, an electric field coupled with powerful clouds and electric forces play a cardinal role in supporting this huge mas...

Arctic cyclone activity is analyzed in 11 year (2000–2010), 3-hourly output from the Arctic System Reanalysis (ASR) interim version. Compared to the global modern era reanalyses (European Centre for Medium-Range Weather Forecasts Reanalysis (ERA)-Interim, Modern Era Retrospective Analysis for Research and Applications, and National Centers for Environmental Prediction-Climate Forecast System Re...

As n precursor to numerical simiilntion of tropical cyclones with multilevcl vertical resolution, a linear model in which the thermodynamic equation is applied at two levels is considered. Eigenvalue solutions for conditional and unconditional heating are compared.

North Australian tropical savanna accounts for 12% of the world’s total savanna land cover. Accordingly, understanding processes that govern carbon, water and energy exchange within this biome is critical to global carbon and water budgeting. Climate and disturbances drive ecosystem carbon dynamics. Savanna ecosystems of the coastal and sub-coastal of north Australia experience a unique combina...

[1] Midlatitude cyclones are important contributors to boundary layer ventilation. However, it is uncertain how efficient such systems are at transporting pollutants out of the boundary layer, and variations between cyclones are unexplained. In this study 15 idealized baroclinic life cycles, with a passive tracer included, are simulated to identify the relative importance of two transport proce...

The impact of the extratropical transition (ET) of tropical cyclones and baroclinic cyclogenesis in the Western North Pacific (WNP), Atlantic, and Southern Indian Ocean (SIO) basins on the predictability of the downstream midlatitude flow is assessed using 30 y of cases from the Global Ensemble Forecast System (GEFS) Reforecast Version 2. In all three basins, ET is associated with statistically...

[1] The quality of the retrieved temperature and moisture profiles acquired from the Atmospheric Infrared Sounder (AIRS) aboard the NASA Aqua spacecraft was evaluated by comparing the data with dropsonde observations obtained from NASA African Monsoon Multidisciplinary Analyses (NAMMA 2006) and international THORPEX Pacific Asian Regional Campaign (T‐PARC 2008) field programs. Results indicate ...
