The invention discloses a global climate vector field data visualization method based on VR and a gesture interaction technology. The method comprises the steps that a 3D environment is set up, and a scene containing an earth and a cosmic background is designed; map data acquired from the Natural Earth is added to the designed earth, and then weather data is downloaded from a global forecasting system operated by the National Weather Service and is decoded; next, the data is subjected to wind direction quick reference and geostrophic wind approximate solving, vector wind is projected to the designed earth, and finite difference approximation is used for estimating distortion in an interpolation process; and last, interaction demands are designed, and various gestures are defined according to the demands. Through the method, global climate changes are simulated more realistically, the perceptibility and authenticity of a model and the data are enhanced, information details at a higher level are obtained, a user can truly feel a research object standing in front and can operate the research object through gestures, and therefore a visual spatial data visualization analysis environment is constructed.
