11. Impressions of listing the services of each company

・ As so-called expression of the weather"Weather" "Weather forecast" "Result of numerical calculation"Also, there are differences in what we usually think of as weather forecasts together, and each company uses different words (for example, the words "weather" and "weather forecast" are the same page) (Some cases have been mixed)It is necessary to be aware in advance of confusing points for general users who are not familiar with legal and industry customsI thought.

-Peak weather, especially pinpoint forecastTo announce what is saidSpecific forecastAlthough some services show that they need to be "specifically," they do not necessarily have to be "directed forecasts", and depending on the conditions "General forecastIt also seems to be. There is an easy-to-understand commentary on the "Frequently Asked Questions" page of the Japan Meteorological Agency.

・ At the beginning of the "Frequently Asked Questions" page, there is an explanation of the weather forecast definition. If you are not a weather forecaster in the process of investigating this time,It is impossible to transmit any "forecasts" or what is forecasted to an unspecified number of peopleA website that says "Sometimes" was found. this is,Specific user(User definition: target for which a contract has been signed)Announce your own expected results"To another corporationIt is not necessary to take permission unless it is provided. It seems like.

・ As a supplement, “The forecast of the Meteorological Agency announcement and the permit companyIf you just explain the forecast, you do not need the forecasting business permission. "There is. It was very helpful because I had the impression that I could not explain the forecast itself if I was not a weather forecaster. Certainly, if this is not recognized, there will be restrictions on displaying the widget or blog part that displays the weather on the home page, and there will be problems in adding your own opinion and commentary .

・ The nuances of “This is not a weather forecast but a numerical calculation result,” which many of the weather forecasting companies refuse, and this is a human being, as described in the Japan Meteorological Agency.AnticipationAdded ""forecastThere is no doubt that this is the case, but if you carefullyCalculation results based on various observation data."Numerical calculation results (we call them numerical forecasts in the Japan Meteorological Agency)" sometimes sees and hears the notion that it is more unreliable than "weather forecast", or that it requires attention, but it can not be generally stated I thought it was not there.

・ Even if it is the result of numerical calculation, it is not a bad thing to think about yourself on the basis of the weather of the day, whether it is the mountain area or the plain area.I felt it would be much more useful than forecasting the weather based on weak information with insufficient knowledge of the weather.

It became a long time, but it was a good opportunity to deepen our understanding of each company's services, including the fundamental part of what the weather forecast is. We hope this list is helpful.

Then, by all means, safe and fun climbing and camping!
