The study and applications of photochemical-dynamical gravity wave model Ⅰ——Model description
《Science China Mathematics》2002年第z1期167-174,共8页徐寄遥 马瑞平 A.K.Smith 
National Natural Research Project (G2000078407); the National Natural Science Foundation of China (Grant Nos. 49974038, 49990454).
A two-dimensional, nonlinear, compressible, diabatic, nonhydrostatic photochemical- dynamical gravity wave model has been advanced. The model includes diabetic process produced by photochemistry and the effect of grav...
