Longstreth, T. Morris (Thomas Morris)
Weather forecasting
But, although the Weather Bureau,--like the Christian Church and other
things that have had to combat superstition at every step--has grown
slowly it has grown surely and its work is being recognized more widely
and relied upon more understandingly every month. It was an American
scientist who discovered the rotary motion of cyclones and their
progressive character, but due to the conservative nature of our
Government three other nations had established weather services before we
had. In 1870 the War Department was authorized to start a system of
observations that would permit of a rough sort of forecasting. The
forecasts proved of so much value to shippers and sailors that the work
was handed over to the Department of Agriculture and enlarged (1891).
To-day every part of our country contributes to the knowledge of existing
weather conditions.
At 8 A. M. observations are made at hundreds of stations and wired to the
Central Office at Washington. The Chief there, knowing these conditions,
is enabled to locate a storm, to gauge its rate of speed, to learn its
course, and to measure its intensity. He can dictate storm warnings and be
sure that within an hour every sailing master will have a copy. He can
detect a cold wave at its entrance into our territory and know that within
an hour every shipper, every truckster (who has signified that he wishes
to be informed) will have the facts that will save him money.
At 8 P. M. the same stations telegraph the changed conditions, and if any
very violent disturbance is in progress an observation is made at noon.
Besides the Washington distributing station there are 1700 others from
which warnings are sent by telegraph, telephone, or mail. There are
100,000 addresses on the mailing list and 5,000,000 telephone subscribers
can get them within an hour. The newspapers reach many millions. And all
this at a cost of 1-1/2 cents a year. If we, in a fit of generosity,
should pay 2 cents, or even 2-1/2 the Government would be enabled to work
out many of the larger problems awaiting only a larger appropriation to be
attacked.
