Recent Studies on Changes in Track and Convection Associated with Tropical Cyclone Landfall

Tropical Cyclone Research and Review, 2012
: As a tropical cyclone makes landfall, changes in friction and moisture as well as the presence of topography will modify the flow and subsequently the convection associated with the tropical cyclone. As a result, the distribution of potential vorticity

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

Quarterly 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 ...

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 ...

Statistical evidence links exceptional 1995 Atlantic hurricane season to record sea warming [PDF]

, 1997
Tropical cyclones rank above earthquakes as the major geophysical cause of loss of life and property (Bryant, 1991; Houghton, 1994). In the United States alone, the damage bill from mainland landfalling hurricanes over the last 50 years averages $2.0 ...

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 Structure and Motion [PDF]

, 1999
To improve tropical cyclone track and intensity prediction through a research program combining high resolution modeling and detailed observations to investigate physical processes by which the motion and structure of a tropical cyclone is modified ...

Marine heatwave events strengthen the intensity of tropical cyclones

Communications Earth & Environment
Marine heatwaves become more frequent and stronger due to global warming. It is necessary to clarify how and by which process marine heatwaves affect marine weather systems. Here, we examine how marine heatwaves strengthen tropical cyclones.

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

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
