The estimation of tropical cyclone (TC) intensity using Ku-band scatterometer data is challenging due to rain perturbation and signal saturation in the radar backscatter measurements. In this paper, an alternative approach directly taking maximum scatterometer-derived wind speed proposed assess TC intensity. First, center location identified based on unique characteristics stress divergence/cur...

The effects of wind protection on growth and total and marketahle yields of snap hean tPhaseolus vulgaris L.) planted at 2-week intervals through the 1994 and 1995 growing seasons were examined. Research was conducted under nonirrigated conditions at the Shelterhelt Research Area, Univ, of Nebraska Agricultural Research and Development Center (ARDC) near Mead. 'Strike' <white-seeded) and 'Rushm...

A reaction-diffusion model for the propagation of an idealized forest fire is revisited to include the effect of wind on the speed of propagation. We study the existence of one-dimensional travelling wave solutions. When the wind velocity is zero or when the wind blows from the burning region, the existence and uniqueness of the travelling wave is proved. In the case when the wind blows into th...

The Chinese new marine dynamic environment satellite HY-2D was launched on 19 May 2021, carrying a Ku-band scatterometer (named HSCAT-D). In this study, wind products observed by the HSCAT-D were validated comparing with data from U.S. National Data Buoy Center (NDBC) buoys and European Centre for Medium-Range Weather Forecasts (ECMWF) model. statistical results show that winds have good agreem...

Inference rule substitution of equals for equals has been formalized in terms of simple substitution which performs a replacement even though a free occurrence of a variable is captured contextual substitution which prevents such capture and func tion application We show that in connection with pure rst order predicate calculus the function application and no capture versions of the inference r...

This paper deals with a realistic turbine simulator that uses a 20 kW DC motor with an independent excitation and mntmlled hy a microcompiiter. The tiirhine torque and rotation are both simnlated according to wind and load of actually driven generators with any type of rctuql loads. With the help of this simulator it is possible to develop and realise tests in electrical power plants in conditi...

The wind and wave derived from the scatterometer altimeter on board Chinese Haiyang-2B (HY-2B) satellite were systemically evaluated in this study. analysis of matchups between Advanced Scatterometer (ASCAT) winds HY-2B with speeds up to 25 m/s showed a 0.78 Root-Mean-Square Error (RMSE) 0.97 Correlation (COR), superior 1.2 RMSE 0.93 COR HY-2B. Simultaneously, significant heights (SWH) measured...

Wind measurement using spaceborne scatterometers has been used for various scientific and operational purposes. However, the major problem of such measurements is contamination by rain. To improve wind HY-2A scatterometer under rainy conditions, a neural network-based model was established in this study. The almost autonomous that it only needs backscatter coefficient data observation geometry ...
