This study discussed the influence of aerosols on relative frequency positive cloud-to-ground (CG) lightning and its dependence thermodynamic cloud-related factors in Sichuan during warm season from 2005 to 2017. The CG is defined as proportion flashes total flashes. Although density Western Plateau significantly lower than that Basin, higher basin. Convective available potential energy (CAPE) ...

An increasing number of cloud services has been emerging in the recent years. Amazon, gogrid, rackspace, to name a few, are several most popular cloud service providers. Users need a tool to discover the available options and to suggest the most appropriate alternatives. CB-Cloudle, as a cloud service search engine, could satisfy such users’ need. In this work, a centroid-based search engine wi...

Although severe thunderstorms are one of the primary causes of catastrophic loss in the United States, their response to elevated greenhouse forcing has remained a prominent source of uncertainty for climate change impacts assessment. We find that the Coupled Model Intercomparison Project, Phase 5, global climate model ensemble indicates robust increases in the occurrence of severe thunderstorm...

In an effort to shed more light on the formation process of binary stars, we have started a program to study multiplicity among nearby low-and intermediate-mass protostars using the OVRO Millimeter Array. Here, we describe the project and present the first results on the protostellar core in the Bok globule CB 230 (L 1177). At 10 ′′ resolution , the molecular core is resolved into two component...

UNLABELLED ThunderSTORM is an open-source, interactive and modular plug-in for ImageJ designed for automated processing, analysis and visualization of data acquired by single-molecule localization microscopy methods such as photo-activated localization microscopy and stochastic optical reconstruction microscopy. ThunderSTORM offers an extensive collection of processing and post-processing metho...

Design wind loads are partly based on extreme value analyses of historical wind data, and limitations on the quantity and spatial resolution of wind data pose a significant challenge in such analyses. A promising source of recent wind speed and direction data is the automated surface observing system (ASOS), a network of about 1000 standardized US weather stations. To facilitate the use of ASOS...

In this two-part paper, the impact of level-II Weather Surveillance Radar-1988 Doppler (WSR-88D) reflectivity and radial velocity data on the prediction of a cluster of tornadic thunderstorms in the Advanced Regional Prediction System (ARPS) model are studied. Radar reflectivity data are used primarily in a cloud analysis procedure that retrieves the amount of hydrometeors and adjusts in-cloud ...

Coriolis-centrifugal convection (C$^3$) in a cylindrical domain constitutes an idealised model of tornadic storms, where the rotating cylinder represents mesocyclone supercell thunderstorm. We present suite C$^3$ direct numerical simulations, analysing influence centrifugal buoyancy on formation tornado-like vortices (TLVs). TLVs are self-consistently generated provided flow is within quasi-cyc...

background: dendritic cells (dcs) are the most potent stimulators of primary t cell responses and play a key role in immune reactions after stem cell transplantation. very little is known about the cord blood (cb) dendritic cells and their potential involvement in the low incidence and lower severity of acute graft-versus-host disease after cb transplantation.   objectives: the aim of this stud...
