1. A method of real time three-dimensional weather generation in digital radar landmass simulation comprising the steps of:

  • compressing off line digital weather data as a compressed weather data base for the simulation;

    storing the compressed weather data in a database for later access and reconstruction for the simulation;

    synchronously ad continuously accessing the compressed weather data from said database and reconstructing and temporarily storing the data;

    inputting weather top, weather bottom and depression angle data;

    inputting weather expansion, rotation and translation data;

    computing weather expansion, rotation and translation as ownship approaches a weather mass in a weather simulation;

    computing from said weather top, weather bottom and depression angle data and from the computed weather expansion, rotation and translation a modified attenuation distance; and

    processing the temporarily stored weather data with said modified attenuation distance to produce a real time simulation of weather.
