The optimum time and space distribution of upper-air observations is considered in connection with the detection and prediction of instability lines-a mesoscale phenomenon. It is shown that the optimum spacing of observational stations is not only a function of the scale of the phenomena to be detected but of observational and analytical errors as well. When these errors are considered the opti...
