Water pumping analysis and experimental validation of beach well infiltration intake system in a seawater

Huan ZHANG,Shu LIU,Xuejing ZHENG,Gaofeng CHEN

Frontiers in Energy 2015, Volume 9, Issue 3,   Pages 335-342 doi: 10.1007/s11708-015-0365-7

Abstract: Based on energy conservation equation and Darcy’s law, a model of beach well infiltration intakeIn addition, the influencing factors of pumping water of beach well were also analyzed.The pumping water was found to increase when the distance between the beach well and the impervious boundarybecomes longer, when the distance between the beach well and the supplying water source shortens, whenthe diameter of the beach well enlarges, and the drawdown enlarges.

On Subtropical Anticyclone and High Temperature Drought in Relation to the Earth Nutation and Rotation

Wei Ming,OuYang Shoucheng

Strategic Study of CAE 2007, Volume 9, Issue 8,   Pages 40-46

Abstract:

In view of the effective results about the long term disaster weather prediction based on the variation of the earth rotation in the recent 10 years,  the authors try to explore the deep reason of major disaster weather with the re lationship among the earth nutation,  rotation and atmospheric change.  The relationship between the subtropical anticyclone and subtropica l easterlies is discussed,  aiming at the problem of high temperature and drought in the globe.  Further more,  the comparison analysis is made on earth nutation and the variation of rotation.  The research results show that the reasons of important disaster weather not only involre atmosphere itself,  but have some variation information of earth movement which could be used for the weather forecast.

Keywords： nutation     earth rotation     subtropical anticyclone     inverse rolling sinking     drought
