the moisture flux convergence (mfc) and relative humidity in dusty days at different times and levels over the alvand mountain was investigated. the required basic data for the years 2009-2012, including relative humidity, visibility and synoptic codes, were gathered from hamadan synoptic station, while sea level pressure, uwind, vwind and specific humidity data were gathered from ncer/ncar sit...

This paper documents the TIGER 700 RMRS Treebank which has been obtained as the result of a software project. The treebank is a semantic projection from a subset of the TIGER Dependency Bank and was derived automatically, using treebank conversion methods. In a second phase, it will be manually validated and corrections will be made as necessary, supported by an interactive editing tool.

The ground-based millimeter wave ozone spectrometer (GROMOS) has been continually measuring middle atmospheric ozone volume mixing ratio profiles above Bern, Switzerland (46.95N, 7.44E, 577 m), since 1994 in the frame of NDACC. The high temporal resolution of GROMOS (30 min) allows the analysis of short-term fluctuations. The present study analyses the temporal perturbations, ranging from 1 to ...

A weak tropical storm (Gabrielle in 2001) experienced a 22-hPa pressure fall in less than 3 h in the presence of 13 m s ambient vertical wind shear. A convective cell developed downshear left of the center and moved cyclonically and inward to the 17-km radius during the period of rapid intensification. This cell had one of the most intense 85-GHz scattering signatures ever observed by the Tropi...

The effective patterns and mechanisms of synoptic systems during the wet and dry spells in Midwest of Iran(MWI) analyzed and discussed on seasonal scales from 1974 to 2003. Synoptic Analysis is based on synoptic chartson Sea Level Pressure (SLP), 850 and 500 Hpa levels. The results of synoptic analysis show that dry spells in MWIare mostly corresponded to Azores High (AZH) intensifying and its ...

Data on 211 crossbred gilts were utilized to investigate the effects of season of birth, presence or absence of boars and number of gilts per pen on age and weight at puberty. The gilts were allotted to treatments at an average age of 140 days. Gilts born in the fall reached puberty at a younger age and a lower weight (P<.01) than those born in the spring. There also was a higher incidence of "...

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...
