Happy Spring Equinox! Are You Weather Ready for the Season?

While many welcome the blooming flowers and chirping birds as signs of spring, the official arrival of the season hinges on a celestial event: the vernal equinox. This astronomical phenomenon marks a turning point in the Earth's journey around the Sun, ushering in a period of change and renewal. But what exactly is the equinox, and how does it influence our weather patterns?

What's in a Name?

The word "equinox" comes from the Latin words aequus (equal) and nox (night). True to its name, the vernal equinox signifies a near-equal balance between day and night.

As the Earth's axis tilts at an angle throughout the year, the Sun's direct rays fall on different hemispheres. On the day of the equinox, however, the Sun crosses the celestial equator, causing both the Northern and Southern Hemispheres to receive roughly the same amount of sunlight. This balance, however, is slightly tipped — due to atmospheric refraction, the Sun appears a bit higher in the sky even after crossing the equator, leading to a day that's just a tad longer than night in the hemisphere experiencing spring.
