Seasonal variations of snow cover fraction (SFC) over the Tibet Plateau (TP) are examined using data acquired from Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra spacecraft. In this study, we first evaluate accuracy MODIS high‐resolution by comparing with in‐situ Chinese observations. Results show that overall is about 90% TP area. Statistical analysis then performed during 2000–2006. It found most persistent located in southern and western edges within large mountain ridges...
The three-dimensional global wind field is the most important remaining measurement needed to accurately assess dynamics of atmosphere. Wind information in tropics, high latitudes, and stratosphere particularly deficient. Furthermore, only a small fraction atmosphere sampled terms profiles. This limits our ability optimally specify initial conditions for numerical weather prediction (NWP) models understanding several key climate change issues. Because its extensive heritage (since 1968)...
Abstract Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific societal interest mountain meteorology. To address needs help improve the prediction weather, U.S. Department Defense has funded a research effort—the Mountain Terrain Atmospheric Modeling Observations (MATERHORN) Program—that draws expertise multidisciplinary, multi-institutional, multinational group researchers. The...
Abstract An advanced research version of the Weather Research and Forecasting (ARW) Model is used to simulate early rapid intensification Hurricane Emily (2005) using grids nested high resolution (3 km). A series numerical simulations conducted examine sensitivity simulation available cloud microphysical (CM) planetary boundary layer (PBL) parameterization schemes. Results indicate that are very sensitive choice CM PBL schemes in ARW model. Specifically, with different schemes, simulated...
Abstract The performance of an advanced research version the Weather Research and Forecasting Model (WRF) in predicting near-surface atmospheric temperature wind conditions under various terrain weather regimes is examined. Verification 2-m 10-m speed direction against surface Mesonet observations conducted. Three individual events strong synoptic forcings (i.e., a frontal system, low-level jet, persistent inversion) are first evaluated. It found that WRF model able to reproduce these...
Abstract The fifth-generation Pennsylvania State University–National Center for Atmospheric Research (PSU–NCAR) Mesoscale Model (MM5) is used to simulate Hurricane Bonnie at high resolution (2-km spacing) in order examine how vertical wind shear impacts the distribution of motion eyewall on both storm and cloud scale. As many previous studies, it found here that produces a wavenumber-1 asymmetry time-averaged rainfall. Several mechanisms this are evaluated. qualitatively consistent with an...
Abstract Tropical cyclone (TC) outflow and its relationship to TC intensity change structure were investigated in the Office of Naval Research Cyclone Intensity (TCI) field program during 2015 using dropsondes deployed from innovative new High-Definition Sounding System (HDSS) remotely sensed observations Hurricane Imaging Radiometer (HIRAD), both on board NASA WB-57 that flew lower stratosphere. Three noteworthy hurricanes intensively observed with unprecedented horizontal resolution:...
The effectiveness of a four-dimensional variational data assimilation (4DVAR) technique for creating "bogus" vortices in numerical simulations hurricanes is evaluated this study. A series experiments conducted to generate initial Hurricane Georges and Bonnie (1998) the Atlantic Ocean by assimilating bogus sea level pressure wind information into mesoscale model (MM5). Several different strategies are tested investigating sensitivity vortex representation type information. While some results...
Abstract Accurate forecasting of a hurricane’s intensity changes near its landfall is great importance in making an effective hurricane warning. This study uses airborne Doppler radar data collected during the NASA Tropical Cloud Systems and Processes (TCSP) field experiment July 2005 to examine impact observations on short-range numerical simulation track changes. A series experiments conducted for Hurricane Dennis (2005) landfall. Both reflectivity radial velocity–derived wind fields are...
Severe degenerative mitral regurgitation (DMR) can cause a poor prognosis if left untreated. For patients considered at prohibitive surgical risk, transcatheter edge-to-edge repair (TEER) has become an accepted alternative therapy. The DragonFly valve system is innovative evolution of the TEER device family to treat DMR.
Background Patent foramen ovale (PFO) is among the most common congenital heart defects. Over last two decades, number of research publications on PFO has increased. This study aims to identify and describe current state, hotspots, emerging trends in over previous 20 years using bibliometric analysis visual mapping. Methods The Web Science Core Collection was searched for all research, which were then included study. CtieSpace, VOSviewer, Excel software used visualize general information,...
Transcatheter edge to repair (TEER) has been proven be safe and effective for mitral regurgitation (MR) caused by acute myocardial infarction (AMI). However, some specific conditions, such as papillary muscle rupture complicating AMI, the feasibility of TEER is not yet fully determined. A 74-year-old woman with coronary disease developed MR heart failure after AMI. Transesophageal echocardiography confirmed severe due rupture. The patient underwent emergency TEER, which successfully reduced...
