Impact of the Westerly Jet on Rainfall/Runoff in the Source Region of the Yangtze River during the Flood Season
Published 2020-01-01“…When the intensity of the WJ over the key region is greater (less) than normal, the jet position moves northward (southward), and the easterly (westerly) wind anomalies over the region to the west of the SRYR become unfavorable (favorable) to the transport of water vapor from high-latitude regions to the SRYR. In addition, the southerly wind over the equatorial region cannot (can) easily advance northward, which is unfavorable (favorable) to the northward transport of water vapor from the low-latitude ocean. …”

A Universal Hurricane Frequency Function
Published 2010-01-01“…Evidence is provided that the global distribution of tropical hurricanes is principally determined by a universal function H of a single variable z that in turn is expressible in terms of the local sea surface temperature and latitude. The data-driven model presented here carries stark implications for the large increased numbers of hurricanes which it predicts for a warmer world. …”

Interference source single satellite location method based on movable antenna with spot beam
Published 2016-09-01“…An interference source single satellite location method based on movable antenna with spot beam was proposed for GEO satellites.In this method,a mapping relationship between orientation of interference and antenna gain is first established with the function of antenna pattern.Equations were established to calculate the interference signal link combining the orientation information of center of movable spot beam and the intensity of interference signal which derived from moving the beam several times.The orientation of interference was obtained by solving the equations with the help of particle swarm optimization(PSO).Then the longitude and latitude of the interference source could be calculated,jointly considering the ephemeris and the information of the earth.We made a positioning simulation of the ground interference source with the proposed method.The results validate the effectiveness of this method.…”

Verification of the cell azimuth based on clustering of sampling point and division of switching quadrant
Published 2017-05-01“…Engineering data mainly depends on manual maintenance,and the poor accuracy restricts the development of network planning optimization.Aiming at the cell azimuth in engineering data,the simulated azimuth of the cor-responding cell was calculated by using the sampling point clustering algorithm and the switching quadrant partition-ing algorithm by collecting the measurement report data and the switching statistical data of the network management system.By comparing the simulated azimuth angle and the actual azimuth angle,the existing problems were found,which could be used to guide the data updating and engineering rectification.Through the actual verification of the current network,the research method has achieved good application effect.Similarly,the study can be applied to the latitude and longitude of engineering data,which has a strong reference value.…”

Early warning prediction of external force destruction in transmission lines based on automatic clustering model
Published 2019-03-01“…The external force destruction has become a major threat to the safe and stable operation of overhead transmission lines,bringing difficulties to the defense and early warning work.In order to solve the problem that the traditional clustering center is difficult to accurately determined and susceptible to abnormal points,an automatic clustering method for data analysis work of transmission lines was presented,and external damage data was analyzed from time and space latitude.Firstly,the cluster center was initialized in this method by using Canopy algorithm.Then,the optimized K-means algorithm was used to perform clustering.Finally,the effectiveness of this method was proved by experimental analysis.This method will be applied to the GIS module in the power information system,which can realize the spatio-temporal visualization of the analysis results and provide powerful decision support for finding cause of the external force damage of the transmission line.…”
