Make weather forecasts more fun! Trivia and fun facts about weather (1–10)
In the news, they don’t call it bad weather just because it’s rainy or snowy.
How do you feel when you see a rain icon in the weather forecast? Some people might think, “Rain makes me feel gloomy,” “I won’t be able to go out,” or “I need to prepare an umbrella.” On the other hand, for those whose work depends on it or who love rain and snow, it may be a day they’ve been looking forward to.
In news and weather forecasts that are watched and listened to by people in many different situations, they don’t typically call rainy or snowy days “bad weather.” Those who predict the weather avoid making subjective statements.
Instead, they use terms like “unsettled,” “a downward turn in the weather,” or “the weather will deteriorate” to describe rainy or snowy days.
Raindrops are shaped like steamed buns.
When you hear “the shape of a raindrop,” what shape do you imagine? Most people probably think of a teardrop shape, or perhaps a vertically elongated oval.
But in fact, the shape of a raindrop is like a steamed bun.
By “steamed bun,” I mean the kind you start craving in winter—the ones sold at convenience store entrances.
The reason for this shape is that as raindrops fall to the ground, air resistance flattens their bottom.
Besides “steamed bun-shaped,” it’s also sometimes described as “manju-shaped.”
In “near normal,” the term “normal” refers to the average value over the past 30 years.
On the news weather forecast, you often hear phrases like “around the normal” or “higher/lower than normal,” right? Do you know what this “normal” refers to? It actually means the average over the past 30 years.
This average is calculated from meteorological data spanning from the year whose last digit is 1 to the year, 30 years later, whose last digit is 0.
It is updated every 10 years.
For example, the averages used from 2011 to 2020 are based on data from 1981 to 2010.
The averages used from 2021 to 2030 are based on data from 1991 to 2020.
There are as many as 96 types in the international weather classification.
How many types of weather do you think there are? The ones that come to mind are sunny, cloudy, rain, snow, and thunder… right? But internationally, there are said to be as many as 96 defined types of weather.
In Japan, by the way, they’re classified into 15 types, including things like sleet, ground blizzard, and graupel.
Even 15 feels like a lot, and probably only a few people remember them all.
When you travel abroad and check the weather forecast, try looking for any unusual weather terms!
The typhoon’s winds are stronger on the right side relative to its direction of movement.
A typhoon brings winds so strong you can’t even stand and pounding, driving rain.
When a typhoon forms, many people likely pay close attention to the weather forecast.
The strength of the wind in a typhoon varies depending on direction.
A typhoon involves two types of wind: winds spiraling counterclockwise toward the center, and the steering flow that moves the typhoon itself.
On the right-hand side of the typhoon’s path, where both the inward-spiraling wind and the steering wind blow in the same direction, the wind becomes stronger.
On the opposite side, the inflow and the steering wind collide and partially cancel each other out, so the wind weakens.
