The Effect of Wind upon the Tide. 
The effect upon the tide in the river is probably entirely 
indirect, that is to say, it does not check or assist the tide once 
it has entered the river. On the other hand, the local effect 
may be very great upon the Broads themselves, and may 
give rise to an oscillation of level which might incorrectly be 
•called a tide. Thus Mr. Wheeler states (“ Manual of Tides 
and Waves,” p. 76), that “ a gale blowing on one of the 
Norfolk Broads, half a mile across, caused a difference of 
7^ inches as between one side and the other.” 
The effect of wind upon the river tides is not one which is 
easy to show clearly from observations taken on the river 
itself. Undoubtedly the effect is very great, but it is 
impossible to estimate it accurately except at times when 
•the effect is at its maximum. The irregularities so constantly 
•observed are, no doubt, in most cases due to wind, but they 
■can only be definitely referred to it when the wind is known 
to have been blowing with the force of a gale. Another source 
•of difficulty is that the tides are influenced by the conditions 
■of weather prevailing in the North of England, which may 
be quite different from those observed on the East Coast. 
The most frequent cause of abnormal tides on our coast,
