Visualization of wind data for microscale meteorological model such as the Three Dimensional Wind Field (3DWF) has been traditionally done in graphic packages without much geo-morphology which is the major cause for flow variations. The advanced geographical information system (GIS) over internet such as Google Earth® offers enormous resources in map and image data retrieving/handling, four-dimensional (space and time) data visualization, overlaying, and many other advanced GIS features. Google Earth proved to be the most widely used and user-friendly for this purpose. This poster briefly documents the algorithm of visualization of vertical and horizontal cross section of wind field and the construction of wind direction's 3D flag for wind direction profile display. For user-friendly applications, several Google Earth graphical user interface (GUI) have been designed to offer the user flexibility and simple options in order to generate 3D displays in Google Earth and to save them in a KML file.
