This July and August, the WDBJ7 Weather Center has received numerous photos of green acorns covering the ground across the region. The acorns are green, which indicate the trees are dropping them prematurely. Mature acorns are typically tan and often fall during the months of September and October. While an early acorn drop doesn't always indicate a serious problem with the trees, it can mean they are struggling.
The word âconstantâ is a little misleading since, because of the Earthâs elliptical orbit the intensity of the solar radiation falling on the Earth changes by about 7% between January 1st, when the Earth is nearest the Sun, and July 3rd, when the Earth is furthest from the Sun (figure 1.2).
