Atmospheric and oceanographic sciences generally differentiate between vertical convection and horizontal advection. These disciplines study the atmosphere and the oceans which are both much wider in the horizontal than they are thick in the vertical. Making the distinction between horizontal (i.e. isopycnal, along surfaces of constant density) and vertical (i.e. diapycnal, through density surfaces) therefore makes sense for meteorologists and oceanographers.
In fluid mechanics on the other hand the terminology is often used interchangeably. Their study environment is frequently a tank in a laboratory and therefore is more of a cube compared to the thin oceanic layer on the Earth. In fluid mechanics, advection and convection is the same.
convection
It is called Convection.
convection
convection occurs in fluids such as water and air
Sunspots and convection cells
The antonym for convection is advection. Advection refers to the transfer of heat through horizontal movement of air or water, while convection involves the vertical movement of fluids.

Between conduction and convection in Earth's atmosphere is a process called advection. Advection is the horizontal movement of air mass, which can transport heat, moisture, and pollutants over long distances. It plays a significant role in global weather patterns and can influence local climates.
The opposite of convection is advection. Convection refers to the transfer of heat through the movement of fluid (such as air or water) caused by density differences, while advection is the transfer of properties of a substance by the movement of a different substance, typically involving horizontal movement in the atmosphere or oceans.
Convection is the movement of molecules in fluids. The heat transfer takes place through diffusion and advection. Convection refers to the sum of diffusive and advection transfer. Example includes hurricanes. As far as heating winds the sun warms the earth which in turn warms the air and the warmer air expands becoming less dense than the surrounding air mass. The lighter air rises and it cools due to its expansion at high-altitude pressures.
Energy is transferred within the Earth through conduction, convection, and radiation. In the atmosphere, energy is transferred through processes such as convection, advection, and radiation. In the oceans, energy is transferred through currents, waves, and tides, as well as through processes like conduction and convection.
Energy in the atmosphere flows through various processes such as radiation from the sun, convection, and advection. Solar radiation heats the Earth's surface, causing it to warm the air above it. This warm air rises, cools, and then sinks back down, creating a cycle of energy transfer known as convection. Advection refers to the horizontal movement of air carrying energy from one location to another.
Magma can be displaced by the movement of surrounding rocks (advection), rather than rising and falling as it is heated and cooled (convection).
conduction by itself is slower to heat but conduction and convection is faster to heat
advection
The three main methods of heat transfer are conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between materials. Convection involves the transfer of heat through the movement of fluids such as liquids or gases. Radiation is the transfer of heat through electromagnetic waves.
