Strong convection usually occurs in association with strong mid tropospheric convergence of moist air and thus vertical velocity too is a good surrogate for convective activity. Back-trajectory analysis to the mean location (,10.5uN, 76.5uE) of the sampling stations shows (Fig. 4b) an upward ...
Convection Currents | Overview & Examples from Chapter 10 / Lesson 8 514K Learn the definition of a convection current and discover where it occurs. Understand various convection current examples and find how they work with a diagram. Related...
Core convection occurs in a roughly spherical region of a star. This makes it natural to use spherical coordinates to describe core convection. However, the spherical coordinate system has coordinate singularities at 𝑟=0r=0 and at the poles (𝜃=0,𝜋θ=0,π). Different variables must sa...
The convection that is of interest occurs in the space between the lower part of the caprock and the impermeable rock at the base of the saline aquifer, as shown in Figure 1a. Within the limited space of the saline aquifer, more attention was paid to the vertical development and horizontal...
Forced convection is similar to natural convection in that thermal energy is being transferred using a fluid; however, there is one key difference between the two phenomena: While natural convection occurs due to density differences caused by variations in thermal energy, forced convection occurs when...
Convection occurs when a fluid is heated or cooled either at its boundaries (e.g., daytime heating of ground or nighttime cooling of ocean surface) or in its interior (e.g., clouds). It is of profound importance in atmospheric and oceanic dynamics, particularly in transporting heat from one...
The extent of natural convection depends on several factors as the position and the inclination of the heater or cooler, the boundary conditions, the temperature difference that drives heat transfer, the geometry of the apparatus where heat transfer occurs, the roughness of the surfaces, etc. Most...
In general, the Irminger Sea has shifted towards a state of weaker mid-depth stratification after the strong convection in 2007–2008. Deep convection occurs in the Irminger Sea despite strong initial stratification during severe winters in terms of heat removal from the ocean (for example, winter...
Definition Stagnant lid convection is a form of convection that occurs in a material with strongly temperature dependent viscosity for a viscosity contrast larger than about 10 4 . It is characterized by an upper stagnant layer – the stagnant lid – that forms on top of the convecting layer....
