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...

Atmosphere and ocean general circulation model (AOGCM) experiments for the Intergovernmental Panel on Climate Change Fourth Assessment Report (AR4) are analyzed to better understand model variability and assess the importance of various forcing mechanisms on stratospheric trends during the 20th century. While models represent the climatology of the stratosphere reasonably well in comparison wit...

Prior work has suggested that Rossby wave accumulation in the lower troposphere may be an important mechanism for the development of synoptic-scale disturbances in the western north Pacific in northern summer. This work examines the intraseasonal and interannual variability of wave accumulation by computing the barotropic wave activity flux divergence at 850 hPa for different phases of the Madd...

Based on the atmospheric temperature and dew point difference series of mandatory levels in arid region northwest China, we calculated specific humidity stations at 200, 300, 400, 500, 700, 850 hPa analyzed spatial temporal distribution. The radiosonde is compared with two sets reanalysis data (ERA-interim from European Centre for Medium Range Weather Forecasts Modern Era Retrospective Analysis...

The Tropical Rainfall Measuring Mission (TRMM) and ERA5 reanalysis data are used to research the asymmetric precipitation induced by tropical cyclone (TC) Nada, which made landfall on southeastern coast of Indian Peninsula December 2, 2016. mechanism is analyzed during passage TC. results show that spatial average rate increased a maximum 1.78 mm/hr Peninsula, where vorticity TC center more tha...

A new advanced microwave humidity sounder FY-3D MWHS2 radiance has been assimilated under the clear-sky conditions by implementing its data assimilation interface. The case of tropical storm Ampil in 2018 is selected to address effectiveness new-built module initialization and forecast typhoons. Apart from experiment assimilating both Global Telecommunications System (GTS) data, an with only GT...

In this study, deep convolutional neural network (CNN) models of stimulated tropical cyclone intensity (TCI), minimum central pressure (MCP), and maximum 2 min mean wind speed at near center (MWS) were constructed based on ocean atmospheric reanalysis, as well Best Track hurricane data over 2014–2018. order to explore the interpretability model structure, sensitivity experiments designed with v...
