摘要: Abstract Analytic observations are used to compare the traditional and triangle methods for objective analysis of scalar variables. The method assigns gridpoint values based on distance from grid points each member set observations. Subsequently, spatial derivatives derived by applying a finite-differencing scheme field gridded calculates first-order directly nonoverlapping triangles that formed observations, assigned centroids. By calculating bypasses need finite differencing. Triangle centroid estimates itself simply arithmetic averages three comprising triangle. variable its then treat...
