Evaluation of wind forecasts over Svalbard using the high-resolution Polar WRF with 3DVAR

short range precipitation forecasts evaluation of wrf model over iran

iran has a complex topography and it consists of rugged, mountainous rims surrounding high interior basins. because of this condition, in some cases the nwp output has a significant error from mesoscale variations induced by the diverse topography.  iran, covering an area of about 1,648,000 km2, is located in the southwest of asia approximately between 25° and 40° n and 44° and 64° e. this is p...

Evaluation of Polar WRF forecasts on the Arctic System Reanalysis Domain: 2. Atmospheric hydrologic cycle

[1] The forecast atmospheric hydrologic cycle of the Polar version 3.1.1 of the Weather Research and Forecasting model (WRF) is examined for December 2006 – November 2007. The domain is similar to the Arctic System Reanalysis (ASR), an assimilation of model fields and Arctic observations being conducted partly by the Byrd Polar Research Center. Simulations are performed in 48 h increments initi...

Simulation of heavy rainfall events over Indian monsoon region using WRF-3DVAR data assimilation system

We present the results of the impact of the 3D variational data assimilation (3DVAR) system within the Weather Research and Forecasting (WRF) model to simulate three heavy rainfall events (25–28 June 2005, 29–31 July 2004, and 7–9 August 2002) over the Indian monsoon region. For each event, two numerical experiments were performed. In the first experiment, namely the control simulation (CNTL), ...

Evaluation of NU - WRF rainfall forecasts for IFloodS

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
