Ten Crazy Things You Never Knew About Spring

4. The term “equinox” refers to the one day in both the spring and autumn when the time between day and night is equal. The spring (or vernal) equinox occurs around March 21st. It stems from the Medieval Latin, equinoxium, for Latin aequinoctium the time of equal days and nights ( aequi- equi- + noct- (stem of nox) night + -ium -ium ).

5. Every spring in Australia (when the northern hemisphere is experiencing autumn), a unique cloud formation called Morning Glory clouds appear in the southern part of the Gulf of Carpentaria. This is the only place in the world where Morning Glory clouds’ appearance can be predicted and observed on a regular basis.

6. It’s still unknown what exactly cues bears to end their winter hibernation and leave their dens at spring time. According to the Bear Essentials of Hibernation, “male black bears will typically drop between 15 and 30 percent of their body weight, while lactating mothers can lose up to 40 percent.” Don’t fret, though; over 99% of black bears survive the winter.
