Mesosphere convection
WebAbove approximately 500 km (300 miles), the motion of ions is strongly constrained by the presence of Earth’s magnetic field. This region of Earth’s atmosphere, called the magnetosphere, is compressed by the solar wind on the daylight side of the planet and stretched outward in a long tail on the night side. WebWhich are places on Earth where convection is operating on a grand scale, creating conditions important to life on Earth. at the thermal vents in the rift valleys, in the mantle, …
Mesosphere convection

WebThe mesosphere is an atmospheric layer located between approximately 160,000 to 80,000 feet above sea level. It is the third highest layer of atmosphere and is located directly above the stratosphere and below the thermosphere. The mesosphere is a very cold region of the atmosphere with temperatures ranging from -90°C to -130°C (-130°F to ... Web13 dec. 2024 · with q the heat flow across the top surface. The Nusselt number is the ratio between the surface heat flow q and the heat flow that would be transferred by conduction kΔT/d; since convection is an instability that sets in when the heat can be more efficiently transferred by convection, Nu ≥ 1. In a fluid heated from within, the surface heat flow in …
