The weather forecast says that the highest temperature will be 28 degrees and the lowest temperature will be 22 degrees tomorrow. What I want to ask is that 28 and 22 are definitely not fixed values.

The weather forecast says that the highest temperature will be 28 degrees and the lowest temperature will be 22 degrees tomorrow. What I want to ask is that 28 and 22 are definitely not fixed values. What probability distribution do they obey? /b/3690277.html

The weather forecast not only predicts the weather tomorrow, but also predicts the temperature tomorrow.

Sometimes the highest temperature is predicted, such as 35 degrees, 38 degrees, 4 1 degree and so on. If it is 4 1 degree, it is actually very hot. But I personally measured the noon temperature of 49.5 degrees, which was quite different from the weather forecast.

I asked the teacher this question, and the teacher told us. Set four time points every day, two during the day and two at night. Add up the four collected temperatures and divide by four to get the average temperature.

But that's not what the weather forecast says. The general weather forecast will say "Beijing, sunny, 10 to 20 degrees".

Excuse me, what does 10 degree stand for and how is it measured?

What does 20 degrees represent and how to measure it?

Supplementary question: You don't understand me.

Suppose I measure every hour and get 24 10 degrees. But the temperature reaches 40 degrees every half hour. So should it be recorded as "maximum 10 degree, minimum 10 degree"? (Of course, this is just a hypothesis. )

I don't know how many times I have measured it now. The teacher said it four times before. In other words, the lower the measurement frequency, the more likely it is to miss some data.

I know the definition of temperature very well, and I also know when it is usually the hottest and coldest in a day. I mean, does "maximum temperature" mean the highest value in measured data or the highest value in actual temperature?

"The traditional forecasting method provides services for the public with 24-hour process forecasting for a long time, which is divided into two time periods: day and night. After starting the 6-hour fine forecasting service, the weather forecast is fine for four time periods. The public can know the weather phenomenon, maximum and minimum temperature, precipitation, prevailing wind direction and maximum wind power every six hours within 24 hours, and the precipitation will be accurate to the millimeter.
