Convergence is an atmospheric condition that exists when there is a horizontal net inflow of air into a region. These two air masses have been further divided into two types on the basis of the nature of the surface of the source regions (whether continental or oceanic areas) e.g.
The opposite of convergence is divergence. The opposite occurs for the case of horizontal divergence. We see that divergence is positive when the parcel area grows and is negative when it shrinks. They may move in varying directions and speeds. If convergence at the surface exceeds divergence aloft, the low weakens. The spreading out of air above a region. As air exits a trough and moves towards a ridge it speeds up and divergence occurs. Generally speaking, ascending air often leads to formation of cloud and rain, while subsidence brings fine weather. ESS124 Prof. JinProf.
The area where an air mass develops, its _____ region, determines its characteristics. The greater the difference, the stronger the weather, it is as simple as that. pressure or height changes. Continental Tropical Air Mass. Convergence of winds near the surface are associated with upward motion known in meteorology as convection. Mass convergence (and divergence) measured by the Oklahoma Mesonet indicates rising or sinking air near the ground at a particular location based on the change in wind speed over a certain length.
An air mass that is exceptionally cold and dry . Where the height contours are closer spaced, the wind velocity is higher. Continental Arctic Air Mass. In the bottom diagram below, notice in the diffluent pattern that … The location of the convergence line on a particular day depends on the strength of the valley breeze and the strength of the prevailing winds. Therefore, areas of mass …
Jin--Yi YuYi Yu. Second, as height contours spread apart, a divergence of air occurs. The terms are usually used to refer specifically to the horizontal inflow (convergence) or outflow (divergence) of air. Convergence occurs ahead of upper level ridges and divergence occurs An air mass that is warm and humid. Air masses Tropical Maritime air mass. Maritime Tropical Air Mass. We built a homestead at the convergence of two rivers ; The intersection of three electron beams for red, green and blue onto a single pixel in a CRT. As you know, a strong wind moving into a weak wind is convergence. The difference in cloud bases may be so great that it could be … In the bottom diagram below, notice in the diffluent pattern that strong wind is moving into weaker wind and the air streams are diverging over distance also. — Berkeley. The terms are usually used to refer specifically to the horizontal inflow (convergence) or outflow (divergence) of air. The convergence or divergence of the rays falling on the pupil. This air mass. The convergence of horizontal winds causes air to rise, whereas the divergence of horizontal winds causes downward motion of the air (subsidence). If we try to do that, the fluid will rush out to places where the fluid is less dense. The initial devlopment of the cyclone; the presence of curvature divergence as well as divergence associated with an upper tropospheric jetstreak 4. When the air being pulled from the floor below the fan reaches the ceiling, it has no place to go but out. Noun (wikipedia convergence) The act of moving toward union or uniformity. Maritime Polar Air Mass. In the Northern Hemisphere, air tends to circulate _____ around a high-pressure system and _____ around a low-pressure system. Surface lows generally moves southwest to northeast relative to the Rossby wave configuration. The convergence of horizontal winds causes air to rise, whereas the divergence of horizontal winds causes downward motion of the air (subsidence). An air mass that is cold and humid. Upper-air divergence must be present for a mid-latitude cyclone to form. This is a picture of divergence aloft. Why do I care?
