The relationship between equatorial wave interaction and heavy rainfall in Southeast Asia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines the statistical relationship between co‐occurring equatorial waves and heavy rainfall in Southeast Asia. Heavy rainfall is more closely related to combined wave activity than to individual waves in many regions of Southeast Asia. The figure shows GPM–IMERG rainfall (shading) and ERA5 850‐hPa winds (vectors) composited on days when ...

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

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

open access: yesQuarterly 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 ...

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

open access: yesQuarterly 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

The role of mesoscale weather effects in simulating pyroconvection: A case study of the Santa Coloma de Queralt wildfire

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This large‐eddy simulation study on pyroconvection shows that the added value from resolving the mesoscale explicitly is found in the timing of pyrocumulus formation and circulation changes. The circulation of the convective plume itself is not substantially different between the simulations. Abstract Extreme wildfire events are characterised by strong
