A white froth is present on the lake's surface around the plume when the convective activity momentarily increases. Thunderstorms can pose a threat to aircraft, particularly in the stormy summer months, mainly because of the convective motion of the air within storms. The horizontal width of the condensate falling from the convective cells was much less than the width of the observed mesoscale downdraft60 km compared to150 km. Mantle material can sink at a plate boundary, and then flow back upward farther away, pushing on the crust— a process called small scale convection. Below a certain threshold, they will not be strong enough to overcome the convective mixing of the gas at the surface, and spots will disappear altogether. Options and features, such as the addition of convection heat, probe and sensor cooking, meet the needs of virtually every cooking, heating or drying application. Changes in the thickness, viscosity and conductivity of the outer core in the past could have led to convection patterns that caused the magnetic pole to tilt. The influx of cold air on top of warm, moist air favours the sort of deep convection that creates powerful storms, turning moisture in the air into water on the ground very efficiently. Convection within the red giant dredges the new proto- dust atoms from the core up to the surface. Basically, in both you have the benefit of natural forces such as convection. If the surface is cooled and the air above it warmed, there is less tendency for air from near the surface to rise; reduced convection will tend to lead to fewer clouds and reduced rainfall. But as the core cooled, the convection should have eased enough to kill the field. Indeed, injecting a tracer gas into the moundshowed little evidence of steady, convective air circulation. They also suspect a fluid outer core generates the planet's magnetic field though convection. The solar interior, from the inside out, is made up of the core, radiative zone and the convective zone. Arthur Holmes proposed that the heat in the interior of the Earth, some of which was generated by radioactive decay, could be driving a convection that drags around the continents at the surface. A star during most of its life is a main- sequence star, which consists of a core, radiative and convective zones, a photosphere, a chromosphere and a corona. Now that the flow is configured, we can build the contents of the flow. The residual effects of the cloud clusters are generally ignored even though the area they cover is perhaps an order of magnitude larger than the convective region itself. In convection, hot currents flow upwards. On Earth, heat from the solid inner core drives complex fluid dynamics through convection in the planet's molten outer core, causing an electrical charge which generates a global magnetic field. The machine circulated hot air by convection. Finally, the outermost part of a star's atmosphere is the corona, which if super- hot might be linked with convection in the outer layers. Roiling“ convection cells” of gas dominate this zone. |
