A weather variation forecast information providing system includes at least three atmospheric pressure measuring devices arranged at different positions in a specific region and a data processing device processing the measured atmospheric pressure data. The data processing device includes an atmospheric pressure data acquiring unit consecutively acquiring the measured atmospheric pressure data, an atmospheric pressure gradient calculating unit calculating a two-dimensional atmospheric pressure gradient vector including atmospheric pressure gradients at a given position in the specific region in two directions as elements based on the atmospheric pressure data acquired from three of the atmospheric pressure measuring devices, and a weather variation forecast information generating unit generating the information used to forecast a given weather variation in the specific region. |
