CHAPTER 8: NUMERICAL TRACK PREDICTION MODELS

"The fundamental idea is that atmospheric pressures, velocities, etc, should be expressed as numbers, and should be tabulated at certain latitudes, longitudes and heights to give a general account of the state of the atmosphere at any instant....It is shown that there is an arithmetical method of operating on these tabulated numbers, so as to obtain a new table representing approximately the subsequent state of the atmosphere after a brief interval of time, t say."

Richardson (1922).
