Meteorology, 2023 Better understanding of roll vortices that often occur in the tropical cyclone (TC) boundary layer is required to improve forecasts of TC intensification and the granularity of damaging surface winds. It is especially important to characterize rolls over

Atmosphere, 2023 This study attempts to investigate how future sea surface temperature increases will affect the size (radius of gale-force [17 m s−1] wind at 10 m height; i.e., R17) evolution of tropical cyclones that undergo extratropical transition (ET) through ...

Scatterometer observes extratropical transition of Pacific typhoons [PDF]
Eos, Transactions American Geophysical Union, 1997 From September 15 to 25, 1996, NASA's scatterometer (NSCAT) monitored the evolution of twin typhoons—Violet and Tom—as they moved north from the western tropical Pacific, acquiring features of mid‐latitude storms. The typhoons developed frontal structures, increased asymmetry, and dry air was introduced into their cores. Violet hit Japan, causing death

Evidence of small-scale quasi-isentropic mixing in ridges of extratropical baroclinic waves [PDF]
Atmospheric Chemistry and Physics, 2019 Stratosphere–troposphere exchange within extratropical cyclones provides the potential for anthropogenic and natural surface emissions to rapidly reach the stratosphere as well as for ozone from the stratosphere to penetrate deep into the troposphere ...

Use of threshold parameter variation for tropical cyclone tracking [PDF]
Geoscientific Model Development, 2023 Assessing the capacity of numerical models to produce viable tropical cyclones, as well as assessing the climatological behavior of simulated tropical cyclones, requires an objective tracking method.

North American Fire Weather Catalyzed by the Extratropical Transition of Tropical Cyclones [PDF]
Climate Dynamics, 2021 Abstract When tropical cyclones in the western North Pacific turn into midlatitude cyclones, it often perturbs the jet stream, resulting in amplified flow conditions in the north Pacific and various weather extremes in North America. Thus far, however, the complex impacts of extratropical transitioning cyclones (ETCs) on North American fire ...

Comparative analysis of rainstorms caused by two typhoons with similar path deep inland
暴雨灾害, 2021 Typhoons Bolaven (1215) and Lingling (1913) were two typhoons that went directly north to hit Heilongjiang province and caused heavy rain. Both of them changed in the process of going north to the inland.

Transport timescales and tracer properties in the extratropical UTLS [PDF]
, 2010 A comprehensive evaluation of seasonal backward trajectories initialized in the northern hemisphere lowermost stratosphere (LMS) has been performed to investigate the factors that determine the temporal and spatial structure of troposphere-to ...

A Statistical Model to Predict the Extratropical Transition of Tropical Cyclones [PDF]
Weather and Forecasting, 2020 Abstract This paper introduces a logistic regression model for the extratropical transition (ET) of tropical cyclones in the North Atlantic and the western North Pacific, using elastic net regularization to select predictors and estimate coefficients.
