If both legs are pointed, the instrument known as DIVIDERS and is used principally for measuring distances or coordinates. A graduated line connected to a Current POLE, vapealive used in measuring the velocity of the current. 2. To regulate the line of sight of an optical instrument, comparable to a theodolite, in proper relation to other components of the instrument. While cyclolysis normally happens with a filling (an increase in atmospheric strain), the two terms should not be used synonymously.
While cyclogenesis usually happens with a deepening (a decrease in atmospheric pressure), the 2 phrases should not be used synonymously. While some occluded fronts exhibit this characteristic, they are extra properly known as Cold OCCLUSIONS. One used primarily for observing bearings could also be called a bearing repeater. See additionally LAMBERT CONFORMAL CONIC MAP PROJECTION, MODIFIED LAMBERT CONFORMAL MAP PROJECTION. In a easy conic map projection the cone is tangent to the sphere or vapeduring spheroid, in a conic map projection with two normal parallels the cone intersects the sphere or spheroid alongside two chosen parallels, and in a polyconic map projection a series of cones are tangent to the sphere or vapehowever spheroid.
A map projection by which all angles round any level are appropriately represented, In such a projection the size is similar in all directions about any level. The terms conformal and orthomorphic are used synonymously since neither characteristic can exist without the other. Compasses used for vapeduring navigation are geared up with a graduated compass card for direct indication of any horizontal direction.
See additionally TABULATED AZIMUTH. See additionally SPLITSECOND TIMER. 1. Tabulated altitude interpolated for increments of latitude, declination, vaporfact or hour angle. A modified great-circle track consisting of an preliminary nice circle track from the point of departure with its vertex on a limiting parallel of latitude, a parallel-crusing observe from this vertex along the limiting parallel to the vertex of a remaining nice-circle monitor to the destination.
Ninety levels minus the latitude, the angle between the polar axis and the radius vector locating a degree. Space-polar coordinates outline a point on the surface of a sphere by (1) its distance from a set point at the middle, referred to as the POLE (2) the COLATITUDE or angle between the POLAR AXIS (a reference line by the pole) and the RADIUS VECTOR (a straight line connecting the pole and the purpose)- and (3) the LONGITUDE or angle between a reference airplane by the polar axis and vapewithout a aircraft by the radius vector vaporover and vapeduring the polar axis.
