Study: How Sun influences lightning and thunder activity on Earth

Japanese researchers have taken the first steps to understand how the Sun's rotational cycle influences lightning activity on Earth. The answers were found in diaries dating back to the 1700s. "It is well known that long-term - centennial to...
