스케일 높이란 무엇인가? 스케일 높이 (Scale Height, \(H\))는 대기에서 고도에 따라 압력과 밀도가 어떻게 감소하는지를 설명하는 중요한 물리적 개념입니다. 구체적으로, 스케일 높이는 대기의 압력이나 밀도가 고도 \(H\) 만큼 증가할 때마다 약 \(\frac{1}{e}\) 만큼 감소하는 높이를 의미합니다. 이 개념은 행성의 대기뿐만 아...
Parker Instability Introduction The Parker instability (proposed by E.N. Parker in 1966) is a classic example of magnetic buoyancy instability in astrophysical plasmas. It arises in a gravitati...
What is a Riemann Solver? In the simplest terms, a Riemann Solver is a computational algorithm used to solve a specific type of problem called the Riemann problem. This problem involves finding th...
What is the Riemann Problem? Hyperbolic PDEs often exhibit discontinuous solutions, such as shock waves and contact discontinuities. The challenge lies in accurately capturing these abrupt changes...
