wind ia all cyclonic storms depends upol
the closeness Of the isobars, for the closer the.
are the greater is the difference In pressure ii
a given distance, and consequently the stronge
the wind. Nearly all of our weather Is Of til,
cycl0Dic or aDticyclonie type, and is entirel.
dependent upon the form and distribution 0
the isObars. II is therefore by the aid of is0bar
charts the daily weather map that the lay
man may be able 10 explain weather change
and make his own forecasts of probable atmos
pheric conditions. careful observer may b
able 10 progBostcate with considerable accu
racy, at times, for his immediate locality, bu
his authority for deductions, being based upol
his own personal experience aud observation
must lead TO many errors In judgment Thi
arises from the fact that the weather at an,
place depends upon general cyclonic or anti
cyclOnic conditions which naturally embrace
very large area Of country and can only b
properly shown aud studied on the weathe
map. Therefore to successfully make loca
weather forecasts the observer must know VIVA
