In the present study, it is shown how this neural network classification approach can be used for relating specific patterns at the 500 hPa isobaric surface with levels of P[M.sub.10] in the Cyprus.

9 Although we usually measure height on land against sea-level, the sea is not in fact strictly flat, but has its own topography that is generally measured in terms of the difference in height and the isobaric surface at a specific reference pressure.
The isobaric surfaces show a (geopotential) topography or relief that does not coincide with that of the Earth.
According to the synoptic weather map, it was clear at the observation site caused by the continental high pressure system from August 3rd to 5th with 500 hPa isobaric surface. On August 6th, heavy rain fell over the Bohai Gulf in relation to the east-moving upper air trough.
The isobaric surfaces above the inlet leading edge and that under the cowl lip are due to the wall thickness which leads to additional external shocks.
Shock reflections inside the inlet are quite obvious, as illustrated by the isobaric surfaces of p/[p.sub.0] = 3.7.
The surface wall is contoured by the pressure ratio p/[p.sub.0], whereas the three isobaric surfaces, respectively, p/[p.sub.0] = 2.4, 8, and 23, are contoured by the Mach number.
The effect is due to the deformation of Acadian isothermal and isobaric surfaces by the antiform al cross-fold, and does not represent a true syn-metamorphic inversion.
