The Father of Modern Meteorology
![Page 34: The Role of Computing in Climate Science Dr. Robert Bishop](https://reader035.vdocuments.site/reader035/viewer/2022062804/5681495c550346895db6af49/html5/thumbnails/34.jpg)
Before the Age of ComputingIn 1922, Lewis Fry Richardson, a British
mathematician and meteorologist, proposed an immersive giant globe to numerically forecast weather. This “factory” would employ 64,000 human computers
to sit in tiers around the interior circumference of a giant globe.

Weather & Climate Communities(A Convergence of Methodologies)
• Numerical Weather Prediction (NWP):National Bureaus of Meteorology today: 3~5 days
ECMWF today: 5~10 days Future Goal: increased accuracy, and on to monthly & seasonal level
• Climate modelling: WCRP today: 100~1000 years
Future Goal : increased accuracy, and on to decadal & annual level
• The 10-year Challenge: Seasonal to inter-annual predictions
Global to regional to local forecastingCoarse-grain to fine-grain spatial resolutionExtreme weather early warning
