By using multi - channel observations of olr , hirs - tb12 , erb , vis , ssmr and ssm i on the us satellites , it is analyzed that the global general atmospheric circulation features related to the anomaly of cold vortex over northeast china and it s premonitors are also revealed . it is found that there is an effected chain , which consists of sea ice over northern hemisphere , sea surface temperature in the mid - east equatorial pacific , asia monsoon and local budget of earth radiation in northeast china , on the anomaly of northeast cold vortex . the impacts of each factor in the chain are discussed . the results indicate that the applications of multi - channel satellite observations on research of climate change are of significance 利用美国气象卫星olr , hirs - tb12 , erb , vis , ssmr和ssm i多通道的观测资料，分析了东北冷涡异常年的全球大气环流特征及其关键地区的先兆特征对于东北冷涡异常，发现了有一个由北半球的海冰，赤道东太平洋的海温，亚洲的季风以及东北地区地气系统辐射收支组成的影响链存在。由此讨论了影响链上的各因子对东北冷涡异常的作用。结果表明多通道卫星观测资料的综合应用在气候变化的研究和预测中有着重要的意义。
In this paper , based on the micaps meteorology data during 2000 - 2002 provided by china weather bureau , the routine observation data from march to may in sand - dust weather provided by qingdao weather bureau , and ep / toms satellite observation data , the dry deposition of sand aerosol data from february 2002 to february 2003 in beijing and from may 2001 to december 2001 in qingdao , author analyzed the processes about source , transportation and deposition on the sea in east asia in recent years 本文利用中国气象局提供的2000 2002年micaps气象资料、青岛市气象局提供的2000 2002年3 ? 5月沙尘天气的常规观测资料； ep toms卫星观测资料；北京2002年2月2003年2月和青岛2001年5月2002年12月气溶胶干沉降资料，主要分析了2000 2002年东亚沙尘气溶胶的源地、入海途径、对我国东部海域影响概率和入海通量。
First , under the given boundary condition and reasonable simplified condition , this paper develops radiation transmitting equations in atmosphere applied in infrared waveband and visual light waveband from common equation of radiation transmitting . then , the formula between observation of satellite and net surface radiation is established according to the developed equations , from which it is found that net surface radiation is relative to sun zenith , land surface and cloud albedo , etc . at last , by using data of satellite visual light ( vis ) , infrared 1 ( ir1 ) , infrared 2 ( ir2 ) and water vapor ( ir3 ) channel , sun zenith and net surface radiation , a regression formula is built 本文从大气中太阳辐射传输的一般性方程入手，引入边界条件及简化条件，推导出红外波段和可见光波段的大气辐射传输方程，由此建立起卫星观测辐射与地面净辐射的关系，文章还就卫星观测到的辐射与云量、云高、云的光学厚度、云及地面反照率等之间的关系进行了理论分析，可以帮助更好地理解云对地面净辐射的影响。
Loss of trees in the brazilian rain forest is much worse than had been thought , according to a new study . losses in clear - cut areas where all trees are removed have been monitored by satellite observations , but those were not able to detect the cutting of individual trees in areas where others are left behind 据美联社10月20日报道，以前，在巴西热带雨林的皆伐地区clear - cut areas ，林木一次性被伐光的地区，树木损失情况都被卫星观测系统监控着，但这种方法却发现不了人们对个别树木的砍伐行为。
