What influence do lunar tides bear to our weather?
On what does the permanence of the summer lows over the Rockies depend?
These questions are only samples. Many certainties can be attained by merely complete observations over a longer period of time, others by new systems of observations that await a more generous appropriation. Even the upper air investigations on Mt. Weather, Va., have had to be curtailed. The Bureau’s record has proved it efficient, of enormous benefit to the country, and deserving of the encouragement instead of the depreciation of every citizen.
WHAT THE WEATHER FLAGS MEAN
In every city the Bureau causes flags to be flown from some prominent place so that a glance may show shippers and everybody who may be concerned at the shortest possible notice just what the approaching weather conditions are.
A plain white flag means fair weather.
A black triangle stands for temperature and is always exhibited with some other flag. Its relative position, either above or below indicates higher or lower temperature. Therefore white flag with the black below means fair and colder. The white flag with the black above means fair and warmer.
A white flag with a black square in the center means a cold wave.
A blue flag means either rain or snow.
The blue with the black above would mean rain or snow and warmer.
