Who wrote the following: "Perhaps some day in the dim future it will be possible to advance the computations faster than the weather advances at a cost less than the saving to making due to the information gained. But that is a dream." |

What is the name of the famous American meteorologist who derived the barotropic vorticity equation? |
Jule Gregory Charney |
|
|
Explain in two sentences (no equations) what is the physical interpretation of the barotropic vorticity equation? |
- advection of absolute vorticity
- Lagrangianconservation of absolute vorticity - absolute vorticity conservation law |
|
|
What are the two types of conditions we have to provide for the solution of a partial differential equation? |

|
Give a one sentence physical interpretation of the hydrostatic balance equation. |
A balance between gravity and the pressure gradient force |
|
|
Cleveland Abbe |
- First Chief Meteorologist of the U.S. Weather Bureau - Prepared and issue the first official weather forecast - suggested the introduction of Standard Time and initiated the conference - The Physical Basis of Long-Range Weather Forecast |
|
|
Vilhelm Bjerknes |

weather modification |
|
|
- Barotropic Vorticity Equation (del in the Nabla, ∆ is the Laplace, and J is the Jacobian) - We used these, because in their general form, they are independent of the choice of the coordinates - Second Order Nonlinear partial differential equation |
