Multivariate objective analysis

From Glossary of Meteorology



multivariate objective analysis[edit | edit source]

An analysis procedure based on derivation of an analytic formula containing two or more variables to approximate values of a physical quantity at specified data points.

The resulting formula serves as an interpolating function to estimate the physical quantity between data points. When two independent variables are used, the result is the equation of a surface that allows objective determination of the isopleths. In a typical meteorological application, objective analysis could be used to derive from scattered observations an expression for contour height as a continuous function of latitude and longitude for the purpose of generating a weather map.


  1. In synoptic meteorology, a detailed study of the state of the atmosphere based on observations, usually including a separation of the entity into its component patterns and involving the drawing of families of isopleths for various elements.
