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.

Phenomena such as cyclones, fronts and thunderstorms can cause extreme weather in various regions throughout the world. Although these phenomena have been examined in numerous studies, they have not all been systematically examined in combination with each other, including in relation to extreme precipitation and extreme winds throughout the world. Consequently, the combined influence of these ...

[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...

The formulation and testing of an enhanced Statistical Hurricane Intensity Prediction Scheme (SHIPS) using new predictors derived from passive microwave imagery is presented. Passive microwave imagery is acquired for tropical cyclones in the Atlantic and eastern North Pacific basins between 1995 and 2003. Predictors relating to the inner-core (within 100 km of center) precipitation and convecti...

[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 ...
