Kanatoko cloud and horizontal ring
Before noon on the 14th (Monday), the Circumhorizontal Arc appeared in Maebashi City, Gunma Prefecture. A circumhorizontal arc is a band of seven-colored rainbow-like light visible in clouds high in the sky (also known as a ‘horizontal ring’ or ‘horizontal rainbow’). Today, it appeared as a cumulonimbus cloud (a cumulonimbus cloud that has grown tall and has a flattened top).
Circumhorizontal arcs are caused by the bending of sunlight by high cloud particles (ice crystals). (Due to factors such as differences in the wavelengths of sunlight, colors appear warmer when closer to the sun, and gradually change to cooler colors as they move away from the sun.)
Circumhorizontal arcs are likely to occur on days when there is sunshine and high clouds in the sky. The circumhorizontal arc is particularly visible during the spring and summer months when the sun is at a high altitude and around noon. How regarding looking up at the sky?
Today’s Kanto Be careful of sudden heavy rain and thunderstorms even if it’s sunny
Today’s Kanto region is affected by Typhoon No. 7, and rain clouds are hanging here and there. Even tonight, there will be places where it suddenly starts to rain. Rain clouds move quickly, so even if it’s sunny, it’s a great enemy to be careless. Watch out for sudden heavy rain, lightning strikes, and severe gusts of wind such as tornadoes.
In addition, from tonight to the morning of the 15th (Tuesday) tomorrow, a linear rain belt may occur, and the risk of heavy rain disasters may increase sharply. Please check the latest weather information frequently and prepare for heavy rain.
