Operational numerical weather prediction
Reviews of Geophysics, 1987A variety of analysis and forecast systems have been used routinely over the years to produce numerical weather predictions (NWP) for daily use. The Joint Numerical Weather Prediction Unit of the United States was the first operational organization established in 1955.

Numerical weather prediction over Antarctica
2023Operations in Antarctica are very much at the mercy of the weather. From early explorations using skis and dogs sleds, through to modern large scale operations involving shipping, tractor trains, helicopters and large fixed wing aircraft, operating from modern facilities, all have been sidelined when the Antarctic atmosphere has become hostile.

The weather is of vital importance to life on this planet. A sudden violent storm may cause loss of life, damage to property and great economic loss. A drought in one country may have political repercussions in other countries also. Agriculture and industry, shipping and aviation, communication and recreation are all fields of human activity that would

Numerical Problems Connected with Weather Prediction
1985Large scale atmospheric motions can propagate on vastly different time scales. The time scale of the so called Rossby waves which describe the “weather”is of the order of a day while inertia-gravity waves can have time scales of order] 0 sec. Meteorologically the main interest is in the first type of motion.

Numerical weather prediction (NWP) entails the use of computer models of the atmosphere to simulate how the state of the atmosphere is likely to evolve over a period of several hours up to 1 or 2 weeks ahead. This approach is central to modern operational weather forecasting: it is the improvements in NWP systems that have led to continual improvements

Numerical weather prediction for GATE
Quarterly Journal of the Royal Meteorological Society, 1979AbstractThe results of a few numerical weather prediction experiments that utilize GATE data are presented. Aside from some simple forecasts based on single‐level models, experiments with a multilevel model examine the roles of some of the physical processes.

Abstract Astounding advances in numerical weather prediction have taken place over the last 40 years. Atmospheric models were rather primitive in the early 1960s and were able to yield modest forecasts at best for one day over a very limited domain at only one to three levels in the atmosphere and for only one or two variables.

The quiet revolution of numerical weather prediction
Nature, 2015Advances in numerical weather prediction represent a quiet revolution because they have resulted from a steady accumulation of scientific knowledge and technological advances over many years that, with only a few exceptions, have not been associated with the aura of fundamental physics breakthroughs.

Advanced Numerical Methods for Numerical Weather Prediction
2000Abstract : The long-term goal of this research is to construct the Navy s next generation NWP model using new numerical methods specifically tailored to take full advantage of distributed-memory computers. In order to take full advantage of the new computer architectures the spherical global domain must be partitioned into local sub-domains, or ...
