Lifecycle‐Type Matters for Extratropical Cyclone Precipitation Production

Geophysical Research Letters
In the midlatitudes, extratropical cyclones produce the majority of winter precipitation. Precipitation rates and accumulation depend strongly on both the cyclone intensity and the environmental moisture amount.

Exploiting Aeolus winds in a regional numerical weather prediction model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Aeolus measured winds have proven to be beneficial for global models. However, demonstrating positive impact for limited‐area models has been a challenge so far. For the first time, we have demonstrated a statistically significant positive impact of Aeolus winds in a limited‐area model by using the 4DVar data assimilation technique and the most recent ...

Income and Extratropical Cyclones in New Zealand

, 2021
Aotearoa New Zealand is highly vulnerable to extratropical cyclones because of its unique location in the midlatitude south pacific region. This study empirically investigates the impact of the extratropical cyclones on individual income, combining the ...

A new perspective for future precipitation change from intense extratropical cyclones [PDF]

, 2019
Extratropical cyclones, major contributors to precipitation in the midlatitudes, comprise mesoscale fronts and fine-scale convective storms. Intense oceanic cyclones pose natural hazards, making reliable projections of their changes with global warming ...

Impacts of stratospheric aerosol injection on precipitation and winds associated with extratropical cyclones in the Southern Hemisphere

Environmental Research: Climate
This study seeks to describe the impact of Stratospheric Aerosol Injection (SAI) under climate change scenarios on precipitation and 10 m winds caused by extratropical cyclones in the Southern Hemisphere, using data from three international initiatives ...

Forecast‐Error Diagnostics in Neural Weather Models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Deep learning weather prediction models enable efficient forecast‐error diagnostics through auto‐differentiation and low computational cost. We apply grid‐point relaxation and gradient‐based error sensitivity to identify key forecast‐error sources. Results show that medium‐range forecasts in the midlatitudes benefit most from relaxing the stratosphere ...

Different propagation mechanisms of deep and shallow wintertime extratropical cyclones over the North Pacific [PDF]

, 2023
Extratropical cyclones (ETCs) are three-dimensional synoptic systems in mid- and high latitudes. Previous studies on ETC propagation have typically focused on cyclones identified at a single level.

Mediterranean cyclones are a substantial cause of damaging floods in Corsica

Communications Earth & Environment
Cyclones, whether tropical, extratropical, or of Mediterranean origin, play a crucial role in the Earth’s climate system, affecting environments and populations through strong winds, heavy rainfall, and flooding.

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 ...
