The basis for modern weather forecasting
It is a truth universally acknowledged – at least among non-medievalists – that classical scientific knowledge died with the Roman Empire and had to be disinterred once the Middle Ages were over. This talk will demonstrate that this belief is mistaken, using the example of medieval weather forecasting. Ancient astronomers had no satisfactory answer to the important question of how seasonal weather can vary so much from one year to another and from place to place. Medieval European meteorologists had complex and data-driven answers, based on the work of astronomers and astrologers in the Arab Empire. The models used could produce forecasts for any chosen date and location – but appear magical to modern critics because of their use of astrology.
This talk will look at the methods used in making these forecasts, with practical examples. It will go further and argue that these laid the basis for modern weather forecasting.
