Weather and Sea Intelligence MASINT
The science and art of weather prediction used the ideas of measurement and signatures to predict phenomena, long before there were any electronic sensors. Masters of sailing ships might have no more sophisticated instrument than a wetted finger raised to the wind, and the flapping of sails.
Weather information, in the normal course of military operations, has a major effect on tactics. High winds and low pressures can change artillery trajectories. High and low temperatures cause both people and equipment to require special protection. Aspects of weather, however, also can be measured and compared with signatures, to confirm or reject the findings of other sensors.
The state of the art is to fuse meteorological, oceanographic, and acoustic data in a variety of display modes. Temperature, salinity and sound speed can be displayed horizontally, vertically, or in three-dimensional perspective.

Famous quotes containing the words weather, sea and/or intelligence:
“It is never the thing but the version of the thing:
The fragrance of the woman not her self,
Her self in her manner not the solid block,
The day in its color not perpending time,
Time in its weather, our most sovereign lord,
The weather in words and words in sounds of sound.”
—Wallace Stevens (1879–1955)
“Everywhere, spread all over in characters of living light, blazing on all its ample folds, as they float over the sea and over the land, and in every wind under the whole heavens, that other sentiment, dear to every true American heart,—Liberty and Union, now and for ever; one and inseparable!”
—Daniel Webster (1782–1852)
““... In truth I find it ridiculous that a man of his intelligence suffer over this type of person, who is not even interesting, for she is said to be foolish”, she added with all the wisdom of people who are not in love, who find that a sensible man should only be unhappy over a person who is worthwhile; it is almost tantamount to being surprised that anyone deign having cholera for having been infected with a creature as small as the vibrio bacilla.”
—Marcel Proust (1871–1922)
