Wave potential of meteorological and seismological wave like "Tsunami" is expressed asymptotically by the cylindrical coordinates (r, θ,z) as follows: [numerical formula], where, h is the altitude of tropopause or depth of ocean, λ=2π/k is wave length, and τ=2π/σ is wave period, v=σ/k=λ/τ., and σ^2=g+T/ρ・k^2)k tanh kh, in which ρ is density of the air or waker, T is surface tension, and g is gravitational acceleration. According to the results observed by stratoscope and marinograph, vg=√<gh> is about 288.7m/sec or 204.6m/sec., which shows that corresponding altitude in the air is 8500.5m or corresponding depth of the ocean is 4270.0m. These values represent the properties of tropopause and the Pacific Ocean. The value of generalized capillarity T is calculated by detecting the velocity faster than the gravitational wave, which is the groupe velocity of long waves on the occasion of earthquake, and T is T(10^9ton/sec^2)=4.737×10^<-3> in the air or 8.842 on the ocean.
