potential total lightning data nowcasting

项目摘要

The University of Hannover operates continuously since July 2003 a SAFIR lightning detection network for total lightning in Northern Germany. It is the first network in Germany which detects also intra-cloud besides the usually observed cloud-toground discharges. The objective of the project is to elaborate the potential of this new data source in Germany for the quantitative short-term forecast of heavy convective rainfall and to include the data then in such an operational nowcasting system. Convective precipitation is responsible for approximately half of the annual precipitation in Germany and also often, especially in summer times, for local flooding, but forecasts of heavy convective rainfall usually are unreliable. With total lightning data we expect to contribute significantly to the further development of a comprehensive nowcasting System for convective rainfall in Germany, as so far, not much experience exists here with the use of lightning data, especially not with total lightning data. First own studies confirm some of many already known advantages of total lightning detection systems for nowcasting purposes. The participation in the various observation campaigns of the Schwerpunktprogramm and the provision of the data to the research community is natural part of the project.

自2003年7月以来，汉诺威大学一直在运营一个SAFIR闪电探测网络，用于德国北方的总闪电。这是德国的第一个网络，除了通常观察到的云对地放电外，还检测云内放电。该项目的目标是详细说明德国这一新数据源在强对流降雨短期定量预报方面的潜力，并将当时的数据纳入这一实用的临近预报系统。对流降水是德国年降水量的大约一半，也经常，特别是在夏季，当地的洪水，但强对流降雨的预测通常是不可靠的。总闪电的数据，我们希望大大有助于进一步发展一个全面的临近预报系统的对流降雨在德国，到目前为止，没有太多的经验存在于这里与闪电数据的使用，特别是没有与总闪电数据。首先，我们自己的研究证实了用于临近预报目的的总闪电探测系统的许多已知优点。参与Schwerpunktprogramm的各种观测活动并向研究界提供数据是该项目的自然组成部分。
