What are the advantages of computer forecasting weather?

Electronic computers appeared, and the calculation speed was amazing. The workload of tens of thousands of people a day can be calculated by computer, and it only takes a few minutes to solve the problem. Since then, meteorologists have improved the forecasting equation more and more. In the equation, both the mainland and the ocean are considered; Not only plains and mountains are considered, but also high altitude is considered. Since 1950s, meteorologists have realized a new forecasting method-numerical weather forecast. It is completely calculated and predicted by electronic computer. It can not only measure the short-term weather of 12 hours, 24 hours and 48 hours in the future, but also forecast the medium-term weather of 5 days, 10 days and 15 days. Meteorologists even use the newly discovered special slow waves in the atmosphere to predict the weather in the next month, two months, three months or even longer through accurate calculation.
