J/kg

joules per kilogram (units of CAPE and CIN)

Jet Max (or Speed Max, Jet Streak)

a point or area of relative maximum wind speeds within a jet stream

Jet Streak

a concentrated region within the jet stream where wind speeds are strongest. It sets up wind currents in its vicinity that either enhance or diminish the chance of clouds and precipitation (rising or sinking motion, respectively).

Jet Stream (JSTR)

relatively strong winds concentrated within a narrow current in the atmosphere, normally referring to horizontal, high-altitude winds

Joule (J)

the derived unit of energy or work equal to 1 Newton-meter. Named for James Prescott Joule (1818-1889), a British physicist who studied heat.
