【Being under a starlit sky】

We can see stars more clearly even in cities in winter than we expect,for a side of the Japan which faces the Pacific ocean in winter is covered with continental high pressure zone.Therefore,the weather is apt to become dry.⛄

Contrary to it,in other side,the Japan Sea,there are a lot of days when it's cloudy or it rains in winter.☔

I'm sure the stars in winter are twinkling much brighter.It's a kind of shaking of the air.It's a scintillation.❄

When the ground is being warmed,there is a chill of a cold air mass 寒気団 over the ground.Then the warmth and chill are mixed,convection 対流 is caused,so the air shakes.😃

It resembles flows in a river.If looking at a stone in the bottom of the river,when it flows calmly,we can see the stone clearly,but when it flows quicKly,we'll find it hard to see because of shaking the flow.😃

The air also shakes like the flow in winter,so the starlight looks as if it twinkled.🌠
