Now, can the meteorological observatory predict the outdoor temperature change about every hour the next day?

At present, meteorological departments can simulate the weather trend changes in a certain period of time in the future through numerical forecasting technology, that is, for example, they can accurately calculate the curves of wind, temperature and humidity in the near-surface layer in the next few decades, and the precise accuracy depends on the terrain and weather conditions. Generally speaking, in the case of stable weather, the error of the average temperature per 10 minute will not exceed 1 degree (the military department may have achieved an error of less than 0.5 degree).

However, due to the current national financial resources and social needs, and the unsatisfactory terrain in various places, this result will not be announced to the public.

In order to make such a fine forecast for a certain point alone, it is necessary to make a preliminary observation record and make a correction to the forecast model, which is of use value. According to the demand of forecast accuracy, in addition to investing considerable instruments and equipment, it also needs some manpower to complete targeted special encrypted observation.
