Weather Pattern and the Average

These days it’s unbearably hot everywhere in Sri Lanka, even in Peradeniya (it’s 10 in the night and my thermometer reads 30.2 oC ). A few days ago, I was talking to a couple of Environmental Engineers and they said that the weather these days are unpredictable.

Not only that, they also said something else, that strikes me. For example, the current weather pattern is kind of odd. If you take a full year, in the past,  you get rainy days distributed along the year; but now it’s concentrated (and heavy) at a few patches and then you get long hot days like now. An interesting observation is that the average rainfall for the year is still the same! However, the effect of the current situation is really drastic. Even though you get the same average, now you have floods/landslides (due to the heavy rain) and unusual dry seasons.

When I told this to a student of mine, he said, “this is why sir, I don’t believe in GPA (grade point average)“…

    It recalls the story of a mathematician, who tried to cross the river by getting the average deep of the river
