Scientific term for a contour
Line of constant mixing ratio
Long Wave
wave located in the major belt of the westerlies, characterized by large length and significant amplitude
Basic eccentrincity formula
Ec= V-V -2C
Ec = crictical e. value
V = wind speed south of the closed low
V = wind speed north of the closed low
C = speed of the closed low in knots
temperature advection
Transport of air of different density into a region
layer of solar atmosphere of low density and high temperature which extends far out into interplanetary space by the force of the solar wind
Actual visible surface of the sun
Force which acts to throw a parcel of air outward from the center around which it is moving in a curved path
centrifugal force
streamline within the wind field away from which neighboring streamlines diverge
positive asymptote
Singular point
1) point into which more than one streamline can be drawn
2) about which the streamlines form a closed curve
intermediate short-lived patterns in the transition between wave and vortex
A line of cumulus congestus or cumulonimbus clouds which simulate high latitude cold fronts
Equatorial front
Any line or narrow atmospheric zone across which there is an abrupt change in the horizontal component of the wind parallel to the line
Shear zone
Tropical wave
A trough or cyclonic curvature maximum located within the trade wind easterlies
Critical temperature
The surface temperature which is necessary for the dissipation of fog to occur at a given location
