Simple model for wind field computation from sparse data

An initial attempt to carry out a simple numerical model that will interpolate and smooth the complete wind fields for an arbitrary planar region where only sparse wind data are available is summarized. The model contains four features: any arbitrary planar region with curved or straight line boundaries that do not cross themselves can be treated; the measured wind data can be irregularly distributed in the region; part of the code can be applied to any function that has two independent variables; and irrotational flow is assumed in smoothing the stream function.
