The Pleim-Xiu land-surface model, Pleim surface-layer and Asymmetric Convective Model (Version 2) are now options in version 3.0 of the Weather Research and Forecasting (WRF) model. These physics options were developed for the MM5 mesoscale model and used extensively by the air quality modeling community, so there was a need to extend these physics to WRF. The new physics in WRF are compared to...

We sought to assess the effects of transcatheter closure of atrial septal defect (ASD) on right and left ventricular form and functions, as well as atrial volumes and pulmonary venous flows. We enrolled 25 patients (mean age: 9.02) prospectively who underwent successful transcatheter closure of secundum ASD. We performed transthoracic echocardiography, including two-dimensional, pulsed wave Dop...

Accurate prediction of track and intensity of land-falling tropical cyclones is of the great importance in weather prediction in making an effective tropical cyclone warning. This study examines the impact of initial condition on real time prediction of Bay of Bengal cyclone Viyaru. For this purpose, the customized version of Advanced Research core of Weather Research and Forecasting (ARW-WRF) ...

A NATO-sponsored Advanced Research Workshop (ARW 990-83) on "Coordinate Regulation of Cholesterol Metabolism" was held from October 1-3, 1984, in Sante Fe, New Mexico. The Giovanni Lorenzini Foundation of Italy was also a sponsor. The organizing director was Dr. Ajit Sanghvi, University of Pittsburgh; the co-directors were Drs. Giovanni Galli, University of Milan, Italy, and Terence J. Scallen,...

The Weather Research and Forecasting (WRF) modelling system is developed as a collaborative partnership between the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (the National Centers for Environmental Prediction (NCEP) and the Forecast Systems Laboratory (FSL)), the Air Force Weather Agency (AFWA), the Naval Research Laboratory, Oklahoma U...

Affecting scores of people with seemingly insurmountable and unmanageable costs, tropical cyclones (TCs) are one of the most devastating extreme weather events. In this special issue, we highlight and summarize some of the recent studies that make use of detailed observations and high-resolution numerical models to analyze tropical cyclones from their genesis to post-landfall impacts. Focused a...

Arwˆ bint Aúmad (d. 532/1137) ruled in Yemen for Ž fty-Ž ve years. She played an important political role and at the same time occupied the highest rank in the Ismˆ’“l“ religious hierarchy after that of the imam. Her religious policies, particularly her special relations with the Fatimids, led to the transfer of the Fatimid literary legacy to Yemen, and hence to its preservation following the f...
