Terminologies
  • A typhoon is a mature tropical cyclone that develops in the North Western part of the Pacific Ocean between 180° and 100°E.
  • There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low pressure center, a pre-existing low level focus or disturbance, and low vertical wind shear.
  • Due to their long-term persistence, and the need for a unique identifier in issuing forecasts and warnings, tropical cyclones and subtropical cyclones are given names according to policy. The following are lists from which these tropical and subtropical cyclone names are derived.
  • The main effects of tropical cyclones include heavy rain, strong wind, large storm surges at landfall, and tornadoes.
  • In the Western Pacific, nearly one-third of the World's tropical cyclones are formed there. This makes the basin the most active on Earth. This basin also features the most globally intense storms on record.
  • There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low pressure center, a pre-existing low level focus or disturbance, and low vertical wind shear.
  • GRAPES (a short form of Global/Regional Assimilation and PrEdiction System) is a new generation of multi-scale numerical prediction system developed by China Meteorological Administration (CMA).
  • The semi-implicit and semi-Lagrangian (SI-SL) algorithm is a computational algorithm that is widely used in numerical weather prediction models for the disrectization of the equations governing atmospheric system.
  • In mathematics, the Helmholtz equation, named for Hermann von Helmholtz, is the Partial differential equation
  • Parameterization is used to represent the important physical processes that cannot be explicitly presented in the grid-scale of a numerical model. Parameterization is necessary for several reasons
