First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.
本文首先利用QuikSCAT散射计获取的海面风场资料,利用华盛顿大学行星边界层模式对台风海平面气压场进行反演,并对其强度进行了分析;然后对获取的海面风场,采用变分方法对风场进行分解,分解出无旋和有旋风场,对分解出的有旋风场,再利用UWPBL模式对珊珊和魔羯台风的海平面气压场进行了反演,对所得结果与通常直接反演、NCEP海平面气压场及台风报文资料进行一一对比,结果表明:新的反演定位的方法对台风海平面气压场中心气压的定位精度有了大幅度的提高,此种定位的方法为散射计资料在台风中的实际应用开辟了一条新的思路。

Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.
摘 要:应用混沌理论,分析了网络流量,用单变量的网络流量时间序列重构与网络动力系统等距同构的相空间,进而计算了实际网络的关维数和Lyapunov指数,并证实了网络流量存在混沌特性;据此建立了基于径向基函数神经网络的模型,并对实际网络数据流进行了预测。

Based on the theory proposed by Alkhalifah, that is the reflection wave is determined by normal moveout velocity V of short-spread and anisotropic parameter η under the condition of long-spread data of vertical and lateral isotropic media and non-hyperbolic curve, a method for long-spread data velocity analysis is studied. A 2 step scanning method is used for the hyperbolic and dual parameter scanning of long-spread data.
