Cyclone Classification over the South Atlantic Ocean in Centenary Reanalysis

Atmosphere
Since the beginning of the satellite era, only three tropical cyclones have been recorded over the South Atlantic Ocean. To investigate the potential occurrence of such systems since the 1900s, ERA20C, a centennial reanalysis, was utilised.

Entraining CAPE and a simplified instability index for better assessment of environmental conditions of quasi‐stationary linear precipitation systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Quasi‐stationary linear precipitation systems (QSLPSs) are a major cause of heavy rainfall in Japan, persisting over the same region for more than five hours. This study demonstrates that entraining convective available potential energy (E‐CAPE), which accounts for environmental air entrainment during parcel ascent, more accurately characterises the ...

Dry and Semidry Tropical Cyclones

, 2019
It is widely believed that tropical cyclones are an intrinsically moist phenomenon, requiring evaporation and latent heat release in cumulus convection. Recent numerical modeling by Mrowiec et al., however, challenged this conventional wisdom by finding ...

Recent migration of tropical cyclones toward coasts [PDF]

, 2020
Poleward migrations of tropical cyclones have been observed globally, but their impact on coastal areas remains unclear. We investigated the change in global tropical cyclone activity in coastal regions over the period 1982–2018.

How interference between the North Atlantic Oscillation and the tropical Indo‐Pacific convection modulates wave trains along the subtropical jet: Impacts on the Asian winter climate

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

Tropical Cyclone Losses in the USA and the Impact of Climate Change: A Trend Analysis Based on a New Dataset [PDF]

Economic losses caused by tropical cyclones have increased dramatically. It can be assumed that most losses are due to increased prosperity and a greater tendency for people to settle in exposed areas, but also that the growing incidence of severe ...

Tropical Cyclones and Climate Change

, 2010
Whether the characteristics of tropical cyclones have changed or will change in a warming climate — and if so, how — has been the subject of considerable investigation, often with conflicting results.

Spatial observation‐error correlations for AMSU‐A in all‐sky assimilation: An ECMWF and UK Met Office intercomparison

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Assimilation of AMSU‐A all‐sky observations can be increased up to fivefold if spatial observation‐error correlations are accounted for properly. New correlation estimates derived using data from ECMWF and the UK Met Office reveal that correlation length‐scales are between 75 and 150 km for AMSU‐A channels peaking in the troposphere. This is attributed

Impact of tropical cyclones and socioeconomic exposure on flood risk distribution in the Mekong Basin

Communications Earth & Environment
Tropical cyclones have a big impact on flood risk, and understanding how their activity interacts with population exposure under climate change is critical.

Rapid intensification and the bimodal distribution of tropical cyclone intensity

Nature Communications, 2016
Tropical cyclones rarely achieve high intensities gradually. Here, the authors show that rapid intensification is relevant not only to short-term weather forecasting, but also to the relationship between tropical cyclones and climate.
