Tide occurring when the sun is near equinox. During this period, spring-tide ranges are greater than average.
Industry:Weather
Severe storms in the United Kingdom and North America that are popularly believed to accompany the vernal and autumnal equinoxes. The belief may have originated in the mid-1700s when sailors observed the West Indian hurricanes, which are most frequent at about the autumnal equinox. Statistics of gale frequency do not show that storms are especially frequent in temperate latitudes about 22 September, though it does sometimes happen that the first severe storm of the winter half-year occurs toward the end of September. The belief has been extended by analogy to the vernal equinox, about 21 March.
Industry:Weather
Rainy seasons that occur regularly in many places within a few degrees of the equator at or shortly after the equinoxes. This characteristic of two distinct annual precipitation maxima is found chiefly within a tropical rain forest climate. The main regions are the Congo Valley, the greater Amazon Valley, and the East Indies. In most places, the spring maximum is the greater. Compare zenithal rains.
Industry:Weather
Discharge due to pumping under steady-state conditions; that is, with unchanging drawdown.
Industry:Weather
In general, any theory derived from the assumption of the existence of time invariants.
Industry:Weather
The pressure of a vapor in equilibrium with its condensed phase (liquid or solid). This equilibrium is dynamic in that evaporation and condensation are both occurring but are in equilibrium. It is a function of temperature only and is nearly independent of the existence or density of other gases in a system. It may, however, be dependent on the shape of the surface of the condensed phase. More generally, the equilibrium vapor pressure with respect to small droplets containing soluble impurities may be quite different from the saturation vapor pressure.
Industry:Weather
The hypothetical tide that would be produced by the lunar and solar tidal forces in the absence of ocean constraints and dynamics.
Industry:Weather
The shape that the earth would attain if it were entirely covered by a tideless ocean of constant depth. Compare geoid.
