This article explores the relationship between vertical wind shear (VWS) and tropical cyclone (TC) genesis in Mozambique Channel (MC) for period 1979–2019. Additionally, SST, low-level relative vorticity, 700 hPa humidity upper-level divergence were also analyzed peak cyclogenesis months to explore their contributions. The analyses done using NCEP/NCAR Reanalysis-1 atmospheric fields, monthly O...

The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...

This paper presents the design and characterization of zero bias power detectors, based on MOSFET transistors, integrated in SiGe 55-nm BiCMOS technology from ST-Microelectronics. The working frequency bands circuits are located range (38–55) GHz, dedicated to optimize consumption 5G devices. Three NMOS categories available used (GP, LP, HPA), aim is several detectors different order compare th...

In s coordinates, a variable f e(x, y, s, t) whose horizontal gradient 2=f e is equal to the irrotational part of the horizontal pressure gradient force is referred to as an equivalent isobaric geopotential height. Its inner part can be derived from the solution of a Poisson equation with zero Dirichlet boundary value. Because 2=f (x, y, p, t) is also the irrotational part of the horizontal pre...

Tropospheric temperature trends based on Microwave Sounding Unit (MSU) channel 2 data are susceptible to contamination from strong stratospheric cooling. Recently, Fu et al. devised a method of removing the stratospheric contamination by linearly combining data from MSU channels 2 and 4. In this study the sensitivity of the weights of the two channels in the retrieval algorithm for the troposph...

This study addresses the origin of the synoptic-scale disturbances that occur in the tropical western North Pacific ocean (WP) region in Northern Hemisphere summer. These have been called ‘‘easterly waves’’ and ‘‘tropical depression–type’’ (TD) disturbances. This analysis uses the National Center for Environmental Prediction–National Center for Atmospheric Research reanalysis dataset. By perfor...

Background: In embryological culture dishes, there is a temperature decline when they are removed outside incubators. This study aimed at investigating the effects of this temperature decline within a certain time frame, the type of culture dish with or without the use of laminar air flow and whether it is possible to achieve a sufficient thermal control with the use of a heating stage. Materia...

Data-driven medium-range weather forecasting has attracted much attention in recent years. However, the accuracy at high resolution is unsatisfactory currently. Pursuing high-resolution and high-quality forecasting, we develop a data-driven model SwinRDM which integrates an improved version of SwinRNN with diffusion model. performs predictions 0.25-degree achieves superior to IFS (Integrated Fo...

Satellite-based observations provide great opportunities for improving weather forecasting. Physical retrieval of atmospheric profiles from satellite observations is sensitive to the uncertainty of the first guess and other factors. In order to improve the accuracy of the physical retrieval, an ensemble methodology was developed with an emphasis on perturbing the first guess. In the methodology...
