Environmental influences on the intensity changes of tropical cyclones over the western North Pacific [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
The influence of environmental conditions on the intensity changes of tropical cyclones (TCs) over the western North Pacific (WNP) is investigated through examination of 37 TCs during 2000–2011 that interacted directly with the western North Pacific ...

A Preliminary Analysis of Typical Structures and Microphysical Characteristics of Precipitation in Northeastern China Cold Vortexes

open access: yesRemote Sensing, 2023
The northeastern China cold vortex (NCCV) is the main weather system affecting Northeast China. Based on the precipitation products from the dual-frequency precipitation radar (DPR) onboard the Global Precipitation Measurement core observatory (GPM ...

From Sugar to Flowers: A Transition of Shallow Cumulus Organization During ATOMIC

open access: yesJournal of Advances in Modeling Earth Systems, 2021
The Atlantic Tradewind Ocean‐Atmosphere Mesoscale Interaction Campaign (ATOMIC) took place in January–February, 2020. It was designed to understand the relationship between shallow convection and the large‐scale environment in the trade‐wind regime.

Intraregional Comparisons of the Near‐Storm Environments of Storms Dominated by Frequent Positive Versus Negative Cloud‐to‐Ground Flashes

open access: yesEarth and Space Science, 2021
We gridded 11 years of cloud‐to‐ground (CG) flashes detected by the U.S. National Lightning Detection Network during the warm season in 15 km × 15 km × 15 min grid cells to identify storms with substantial CG flash rates clearly dominated by flashes ...

Update of upper level turbulence forecast by reducing unphysical components of topography in the numerical weather prediction model

open access: yesGeophysical Research Letters, 2016
On 2 November 2015, unrealistically large areas of light‐or‐stronger turbulence were predicted by the WRF‐RAP (Weather Research and Forecast Rapid Refresh)‐based operational turbulence forecast system over the western U.S. mountainous regions, which were

Occurrence of polar stratospheric clouds at Kiruna [PDF]

open access: yesAnnales Geophysicae, 1999
Polar stratospheric clouds (PSCs) are often observed in the Kiruna region in northern Sweden, east of the Scandinavian mountain range, during wintertime. PSC occurrence can be detected by ground-based optical instruments.

Surface winds in the Euro-Mediterranean area: the real resolution of numerical grids [PDF]

open access: yesAnnales Geophysicae, 2004
Surface wind is a variable of great importance in forcing marine waves and circulations, modulating surface fluxes, etc. Surface wind defined on numerical grids is currently used in forecast-analysis, as well as in climatology. Gridded fields, however,
