What are the applications of hydrostatic solvers vs non-hydrostatic solvers in numerical weather prediction?
Earth ScienceAsked by: Madeline Meline What is the difference between hydrostatic and non-hydrostatic? While the hydrostatic model produces vertically-propagating mountain gravity waves, the non-hydrostatic version correctly generates the trapped, horizontally-propagating gravity waves. What is hydrostatic equation in meteorology? ∂z = −gρ. This is the hydrostatic equation. The negative sign ensures that the pressure decreases with increasing
Puzzle using relative dating principles
Earth ScienceAsked by: Linda Young How do you use relative dating principles? Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata). Relative dating does not provide actual numerical dates for the rocks. What
Natural Gas fields as power sources
Earth ScienceAsked by: Linda Young Can natural gas be used for power? The electric power sector uses natural gas to generate electricity and produce useful thermal output. In 2021, the electric power sector accounted for about 37% of total U.S. natural gas consumption, and natural gas was the source of about 32% of the U.S. electric
What processes produced the basalt columns of the Giant’s Causeway?
Earth ScienceAsked by: Ben Young The origin of Giant’s Causeway in Northern Ireland is shrouded in myth & legend. But how did these interlocking basalt columns really come to exist? The process is called columnar jointing. It happens when a layer of molten lava gradually cools by a loss of heat through its surface. What process
Is climate change a vicious circle?
Earth ScienceAsked by: Ben Young What discipline does climate change fall under? Climate Change is studied under the modern discipline of Environmental Science, which is a branch of Earth Sciences or Atmospheric Sciences and crosses many boundaries, incorporating a wide variety of methods and tools. Why are warming temperatures causing a vicious cycle that leads to
Reasons for choosing LES in stead of RANS models?
Earth ScienceAsked by: Angela Foster Why LES is better than RANS? Abstract. Large Eddy Simulation (LES) undeniably has the potential to provide more accurate and more reliable results than simulations based on the Reynolds-averaged Navier-Stokes (RANS) approach. However, LES entails a higher simulation complexity and a much higher computational cost. What is the difference between RANS
