Industry:Weather
Feature in the emission spectrum of solar radiation, identified with neutral hydrogen, that occurs at a wavelength of 121. 567 nm. Because of the extremely low absorption cross section of molecular oxygen at this particular wavelength, this radiation penetrates deep into the earth's atmosphere. It is important to the dissociation of trace gases in the upper mesosphere and to the formation of the lower ionospheric layers by ionizing certain minor atmospheric constituent gases, especially nitric oxide.

Historically, the general statement of 1) the manner in which the winds of a cyclone rotate about the cyclone's center, and 2) the way that the entire disturbance moves over the earth's surface. The formation of this “law” was largely due to the investigations of Brandes in 1926, Dove in 1828, and Redfield in 1831. This knowledge of the general behavior of storms led to the issuance of rules for seamen instructing them in means of navigating to avoid the dangers of storms at sea.

Generally, the effect of any lake in modifying the weather about its shore and for some distance downwind. In the United States, this term is applied specifically to the region about the Great Lakes or the Great Salt Lake. More specifically, lake effect often refers to the generation of sometimes spectacular snowfall amounts to the lee of the Great Lakes as cold air passes over the lake surface, extracting heat and moisture, resulting in cloud formation and snowfall downwind of the lake shore.
