A block diagram and a flowchart of the microcomputer inside the case body 10 are shown in FIGS. 2 and 3. That is, the main configuration is that the pressure sensor 18 measures the current atmospheric pressure, the pressure-voltage converter 19 converts it into voltage, and the AD converter 20 converts analog m into digital air. This atmospheric pressure value Xn is input to the atmospheric pressure-display inner valley selection circuit 21, and the rain probability corresponding to the atmospheric pressure value Xn is selected from the contents of this circuit 217 and the atmospheric pressure value-rainfall probability storage section 22. Then, the selected rainfall probability is displayed on the rainfall probability display 13 through the entire driver 23. In this way, by operating the pressure sensor 18 when necessary, it is possible to know the probability of rain for a predetermined period of time.

Incidentally, the correlation data between the pressure value and the probability of rain to be stored in the rain probability storage faS22 is created from meteorological data, but more precisely, it differs depending on the season. For example, in Osaka and Kanazawa (each observation platform), we tallied all the atmospheric pressure values every 3 hours from July 1, 1980 to June 30, 1980, and calculated the average values for each season, as shown in the table below.

From this table, the maximum difference by season in Osaka is 8.2mb.
It can be seen that there was a change of 8.8 mb at the maximum in Kanazawa. For this reason, the seasonal complete pressure value--rainfall m rate correlation data is stored in the storage section 22, and based on the date set by the date change switch 151C, the function of the annual calendar section 24 is used to store the season to which that day belongs. is selected and set, and the atmospheric pressure value for that season is stored in the storage unit 21.
In addition to selecting the correlation data of rainfall probability, the current crown [L

Furthermore, the correlation data shows that there is a maximum difference of 2.2 mb in Osaka and a maximum difference of 1.5 mb in Kanazawa even between - days, and that the maximum difference is (5) at 9:00 and 21:00 during the day. Considering that it will be minimum at 3 o'clock and 15 o'clock, A
-25 daily variation correction units are provided at the output stage of the -D conversion unit 20. The daily change correction unit 25 adds or subtracts the amount of displacement from the average atmospheric pressure of the day to the inputted atmospheric pressure value, and subtracts the amount of displacement when it is larger than the average atmospheric pressure, and adds the amount of displacement when it is smaller. Through such diurnal variation correction, a more accurate rainfall probability can be determined.
