| Abstract: | On the basis of the spherical grid-point data from the ECMWF,a preliminary dynamical diagnosis is made of the blocking high whichpersisted over the Urals during October 4-27, 1981.Results show thatlike the decaying eddies on the track of the Atlantic and Pacificstorms at their last stage, the upstream eddies in this case have propertiesof upgradient transfer, and similar eddy forcing processes also exist inthe persistence of the Ural blocking. Furthermore, the orographic forcingof the Urals should not be neglected. In conclusion, the eddy forcingand the orographic effect of the Urals play a concurrent role in thepersistence of the blocking. |
