Most the rainfall in the south-west is caused by Atlantic depressions or by convection.

In summer, a large proportion of the rainfall is caused by sun heating the ground leading to convection and to showers and thunderstorms.

( Due to air convection between two panes of glass, the bottom part of the glazing unit is always colder than the top part.

There is an intimate coupling between the movement of the plates on the surface and the convection of the mantle: oceanic plate motions and mantle convection currents always move in the same direction, because the oceanic lithosphere is the rigid upper thermal boundary layer of the convecting mantle.

The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.

In fluid dynamics, laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection.

The energy is carried by either radiation or convection, with the latter occurring in regions with steeper temperature gradients, higher opacity or both.

One wire coil is used as a heater, and the other is used to measure nearby temperature due to convection.

The upper one is the Labrador Sea Water ( LSW ), formed due to deep winter convection in the Labrador Sea.

While the reason for this underabundance is not yet fully understood, one possibility is that convection in stellar interiors can ' overshoot ' into regions where radiation is normally the dominant mode of energy transport.

Another effect of buildings is the blocking of wind, which also inhibits cooling by convection.

Since the tube requires a vacuum to operate, convection cooling of the plate is not generally possible ( except in special applications where the anode forms a part of the vacuum envelope ; this is generally avoided due to the shock hazard from the anode voltage ).

The CNO cycle is highly temperature sensitive, which results in a convection zone about the core that evenly distributes the ' ash ' from the fusion reaction within the core region.

This is in contrast to the Sun, which has a radiation zone centered on the core with an overlying convection zone.

The temperature gradient may also mean Vega has a convection zone around the equator, while the remainder of the atmosphere is likely to be in almost pure radiative equilibrium.

Hot smoke is drawn past the meat by convection for very slow cooking.

However, the actual size and depth of each lens is dependent on the width and shape of the island at that point, the permeability of the aquifer, and the equilibrium between recharging rainfall and losses to evaporation to the atmosphere, transpiration by plants, tidal advection, and human use.

Non-frontal low stratiform cloud can form when advection fog is lifted above surface level during breezy conditions.

When a low stratiform cloud contacts the ground, it is called fog, although radiation and advection types of fog do not form from stratus layers.

Convective heat and mass transfer take place through both diffusion – the random Brownian motion of individual particles in the fluid – and by advection, in which matter or heat is transported by the larger-scale motion of currents in the fluid.

where the advection operator is used.

It is defined to be the ratio of the rate of advection of a physical quantity by the flow to the rate of diffusion of the same quantity driven by an appropriate gradient.

When the pure advection equation, which is free of dissipation, is solved by a numerical approximation method, the energy of the initial wave may be reduced in a way analogous to a diffusional process.

The equation of vorticity ( three components in the canonical form ) describes the material derivative ( that is, the local change due to local change with time and advection ) of vorticity, and thus can be stated in either relative or absolute form.

In general, the evolution of vorticity can be broken into contributions from advection ( as vortex tubes move with the flow ), stretching and twisting ( as vortex tubes are pulled or twisted by the flow ) and baroclinic vorticity generation, which occurs whenever there is a density gradient along surfaces of constant pressure.

In chemistry, engineering and earth sciences, advection is a transport mechanism of a substance or conserved property by a fluid due to the fluid's bulk motion.

An example of advection is the transport of pollutants or silt in a river by bulk water flow downstream.

If the assumptions used to justify this simplified approximation ( i. e. steady-state heat conduction, no convection or advection ) are accepted, we define the simple 1-dimensional heat diffusion equation where temperature T at a depth z and time t is given by the equation:

The process of transport by fluid streaming is known as advection, but pure advection is a term that is generally associated only with mass transport in fluids, such as advection of pebbles in a river.

In the case of heat transfer in fluids, where transport by advection in a fluid is always also accompanied by transport via heat diffusion ( also known as heat conduction ) the process of heat convection is understood to refer to the sum of heat transport by advection and diffusion / conduction.

It became the sole `` subject '' of `` international law '' ( a term which, it is pertinent to remember, was coined by Bentham ), a body of legal principle which by and large was made up of what Western nations could do in the world arena.

So in these pages the term `` technology '' is used to include any and all means which could amplify, project, or augment man's control over himself and over other men.

It is of the utmost importance to the people of America and of the world how their governing President `` ends up '' during the four years of his term.

Only when that term is ended and he is a private citizen again can he be permitted the freedom and the courage to discount the dangers of his death.

`` I may possibly be a greater risk than is the normal person of my age '', the President had said on February 29th of the election year, ignoring the fact that no one of his age had ever lived out another term.

Let us not confuse the issue by labeling the objective or the method `` psychoanalytic '', for this is a well established term of art for the specific ideas and procedures initiated by Sigmund Freud and his followers for the study and treatment of disordered personalities.

Mr. Wagner might or might not be a `` new '' Mayor in this third term, now that he is free of the pressure of those party leaders whom he calls `` bosses ''.

This is done at varying speeds, ranging from the slow and fast Shifte Telli ( a musical term meaning double strings ) to the fastest, ecstatic Karshilama ( meaning greetings or welcome ).

the term of loans for working capital is 6 years.

Interim financing of construction costs is provided by a short term loan from The Chase Manhattan Bank.

For the near term, however, it must be realized that the industrial and commercial market is somewhat more sensitive to general business conditions than is the military market, and for this reason I would expect that any gain in 1961 may be somewhat smaller than those of recent years ; ;

If you would feel happier with full collision insurance, there is a small additional charge, again varying from country to country and depending on the term of such insurance.

The collective by which I address you in the title above is neither patronizing nor jocose but an exact industrial term in use among professional thieves.

for, using the fact that N and N' commute Af and so when R is sufficiently large every term in this expression for Af will be 0.

The only other one I shall mention here is his use of the term capitalism.

This is not, however, the case, and development is a term which we can apply to Hardy only in a very limited sense.

`` Disaffiliation '', by the way, is the term used by the critic and poet, Lawrence Lipton, who has written several articles on this subject, the first of which, in The Nation, quoted as Epigraph: `` We disaffiliate.

This term refers to the ability of a material to resist bending stress and is determined by measuring the load required to cause failure by bending.

Incumbent Richard Salter seeks re-election and is opposed by Donald Huffman for the five-year term.

The term " anthropology " is from the Greek anthrōpos (), " man ", understood to mean humankind or humanity, and-logia (- λογία ), " discourse " or " study.

In some European countries, all cultural anthropology is known as ethnology ( a term coined and defined by Adam F. Kollár in 1783 ).

As amoebas themselves are polyphyletic and subject to some imprecision in definition, the term " amoeboid " does not provide identification of an organism, and is better understood as description of locomotion.
