Abstract Tropical cyclones are among the most devastating natural phenomena that can cause severe damage when undergoing landfall. In wake of poorly forecast 2013 North Atlantic hurricane season, Rossby wave breaking on 350-K isentropic surface has been linked to tropical cyclone activity measured by accumulated energy (ACE). Here, ERA5 data and HURDAT2 used argue latitude 2 potential vorticity...

The study of the Mediterranean cyclones from a climatological point of view has been one of the objectives of the first phase of WMO WWRP MEDEX (MEDiterranean EXperiment) project. It has been revealing itself like a good procedure for extracting conclusions about their characteristics and behaviour. The implementation on ECMWF ERA40 reanalysis of the method for detecting and tracking the cyclon...

Extratropical cyclones are responsible for most of the precipitation and wind damage in the midlatitudes during the cold season, but there are still uncertainties on how they will change in a warming climate. A ubiquitous problem among general circulation models (GCMs) is a lack of cloudiness over the southern oceans that may be in part caused by a lack of clouds in cyclones. This study analyze...

[1] Using infrared satellite imagery, best-track data, and reanalysis data, tropical cyclones are shown to contain a disproportionate amount of the deepest convection in the tropics. Although tropical cyclones account for only 7% of the deep convection in the tropics, they account for about 15% of the deep convection with cloud-top temperatures below the monthly averaged tropopause temperature ...

In this work, we studied the influence of spring (SP) and summer (SU) El Niño events on landfalling tropical cyclones (TCs) in China. The results showed that compared to SU years, average latitude TCs SP years shifted significantly southward TC intensity was stronger, especially post-landfall period. Additionally, more severe storm-level generated over South China Sea made landfall Meanwhile, s...

Now, however, a connection is emerging between warming oceans and severe tropical cyclones. On page 1844, meteorologists report a striking 80% increase worldwide in the abundance of the most powerful tropical cyclones during the past 35 years. The study lends support to another, independent study published just last month that found a similar intensification in the Atlantic and western North Pa...

Extra-tropical cyclones are a relevant feature in the climate at middle and high latitudes. Despite their importance, most studies typically focus only on identified single atmospheric level events close to surface. This paper provides new perspective Southern Hemisphere (SH) cyclone based multilevel tracking algorithm STACKER. The algorithm, using relative vorticity, detects raw tracks levels ...

Frequency and intensity of cyclones over the North Atlantic are investigated using 2 data sets from simulations with the Rossby Centre regional climate model RCA3. The model domain comprises large parts of the North Atlantic and the adjacent continents. RCA3 is driven by ECHAM5OM1 general circulation model data for May to December from 1985 to 2000 and May to December from 2085 to 2100 assuming...

Hourly sea level records from 1954 to 2012 at 20 tide gauges at and adjacent to the Chinese coasts are used to analyze extremes in sea level and in tidal residual. Tides and tropical cyclones determine the spatial distribution of sea level maxima. Tidal residual maxima are predominantly determined by tropical cyclones. The 50 year return level is found to be sensitive to the number of extreme e...
