In the atmosphere, convective momentum transport by small but vigorous (cumulus type) cloudy updrafts can be understood as an interplay of three main mechanisms: Vertical advection of ambient momentum due to subsidence of environmental air that compensates the in-cloud upward mass flux, Detrainment of in-cloud momentum where updrafts stop ...
Momentum: the drag experienced by a rain drop as it falls in the atmosphere is an example of momentum diffusion (the rain drop loses momentum to the surrounding air through viscous stresses and decelerates). The molecular transfer equations of Newton's law for fluid momentum, Fourier's law for heat, and Fick's law for mass are
Absolute angular momentum sums the angular momentum of a particle or fluid parcel in a relative coordinate system and the angular momentum of that relative coordinate system. Meteorologists typically express the three vector components of velocity v = ( u , v , w ) (eastward, northward, and upward).
The first term is equal to the change in temperature due to incoming solar radiation and outgoing longwave radiation, which changes with time throughout the day. The second, third, and fourth terms are due to advection. Additionally, the variable T with subscript is the change in temperature on that plane.
Δp x is uncertainty in measured value of momentum, Δt is duration of measurement, v x is velocity of particle before measurement, v′ x is velocity of particle after measurement, ħ is the reduced Planck constant. The measured momentum of the electron is then related to v x, whereas its momentum after the measurement is related to v′ x ...

A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over ...
