The western boundary current of the North Atlantic subpolar gyre. The current receives considerable input of Arctic Surface Water originating from the East Greenland Current and supplied through the West Greenland and Baffin Currents. Its mean transport is close to 35 Sv (35 × 106 m3 s−1). The current is strongest in February when it carries 6 Sv more water than in August. It is also more variable in winter, with a standard deviation of 9 Sv in February but only 1 Sv in August. Near the Grand Banks it forms the polar front, also known as the cold wall, with the northward flowing Gulf Stream, with which it shares the shedding of eddies. The cold water of the Labrador Current allows icebergs from western Greenland to travel as far south as 40°N, the latitude of southern Italy.

The total observed lightning discharge, generally having a duration of less than 1 s. A single flash is usually composed of many distinct luminous events that often occur in such rapid succession that the human eye cannot resolve them.

The unit of speed in the nautical system; one nautical mile per hour. It is equal to 1. 1508 statute miles (1. 852 km) per hour or 1. 687 ft (0. 5144 m) per second.

The theory that bulk matter, to outward appearances motionless, is composed of huge numbers of atoms and molecules in rapid and incessant motion. By applying the kinetic theory of gases, relations between some of the bulk properties of gases (e.g., the ideal gas law) may be derived and given a molecular interpretation.
Industry:Weather
The time between the center of mass of rainfall and the peak of the resulting hydrograph.
Industry:Weather
The small irregular motions or eddies produced immediately in the rear of an obstacle in a turbulent fluid. For sufficiently high Reynolds number and for very irregular obstacles, the region of lee eddies may extend a considerable distance downstream. As an example in the atmosphere, mountain waves may be thought of as lee eddies.

The Spanish and most widely used term for an east or northeast wind occurring along the coast and inland from southern France to the Straits of Gibraltar. It is moderate or fresh (not as strong as the gregale), mild, very humid, overcast, and rainy; it occurs with a depression over the western Mediterranean Sea. In summer it is rare and weak; in January it is inhibited by the Iberian anticyclone. It is most frequent from February to May and October to December. A levant (French spelling) with fine weather is a levant blanc; in the Roussillon region of southern France (where, as along the Catalonian coast of Spain, it is called llevant) it often brings floods in the mountain streams. The levanter of the Gibraltar Straits is a related phenomenon. Compare leste, lombarde, levantera.
