What is numerical weather prediction?
Q: What is numerical weather prediction?
A: Numerical weather prediction is the way weather forecasts are made using computer models of the atmosphere.
Q: How do these models describe current weather conditions?
A: These models describe current weather conditions using equations that take into account parameters such as pressure, temperature, wind direction and speed.
Q: How are these equations solved?
A: These equations are solved numerically using a dynamic system of partial differential equations.
Q: What programming language are these equations implemented with?
A: Most of these equations are implemented using FORTRAN.
Q: Why are supercomputers used to solve these equations?
A: Supercomputers are used because the number of calculations is huge and they need to be finished quickly.
Q: What physical parameters are taken into account when modelling the weather?
A: Physical parameters such as pressure, temperature, wind direction and speed are taken into account when modelling the weather.
Q: Can this modelling accurately predict the weather?
A: While the modelling is not always completely accurate, it serves as a useful tool for predicting weather patterns in the future.
