For the long-term period in the low-latitude region of the earth, the statistical structure of the height dynamic field at 500 mb during the winter seasons has been studied successfully by using a new correlation function. {ρ (r)=A (r) *EXP [ B(r) ]} where A( r ) and B( r) are two general polynomials. The best selections of the degrees of these two polynomial can be found in the least –squares sense. The results show that this new mixed-type correlation function can yield more accurate fitting than Gandin’s formula (1963) {ρ ( r )=a * EXP (-b*r **2) }. The height dynamic fields at the regular nest grids are then computed and compared with those obtained from the measured data at irregular observational stations. The troughs of the resulting height dynamic fields can be identified very clearly.
