The movement these students followed was described as "Lennonism" and Czech authorities described these people variously as alcoholics, mentally deranged, sociopathic, and agents of Western capitalism. The wall continuously undergoes change and the original portrait of Lennon is long lost under layers of new paint. Even when the wall was repainted by some authorities, by the next day it was again full of poems and flowers. Today, the wall represents a symbol of global ideals
Latitude of the Gulf Stream and the Gulf Stream north wall index Monthly charts of the path of the north wall of the Gulf Stream have been available from surface, aircraft and satellite observations since 1966 and these have been used in several studies of the path’s variability. In 1980, Taylor and Stephens[2] constructed a measure of the latitude of the current, the Gulf Stream south wall (GSNW) index by extracting and analysing time-series of the latitude at six longitudes between 79°W and 65°W, a series of data that continues to the present day. There have been other subsequent studies. In 1994, Drinkwater et al. examined the latitude of the north wall
