It Looks Like Miss La Niña Is Going To Be Joined By Windy Binch SAM For Our Soaked Spring

It’s no shock that we’re in for a soggy spring this year considering La Niña keeps coming back like a dog with a bone. But now it’s joined by a friend, another weather pattern that indicates a higher chance of summer rains. Meet SAM — the new sopping thot on the radar. According to the Bureau of Meteorology, SAM (or the Southern Annular Mode) is currently “strongly positive” which means a belt of westerly winds between Australia and Antarctica known as the “roaring 40s” and “furious 50s” are being pushed south and away from the country. A positive SAM increases the likelihood of rains in eastern NSW, far-eastern Victoria and parts of southern Queensland. But it can also cause parts of southwest and southeast Australia to dry out — just to keep everyone on their toes, I guess. The SAM weather pattern moves through three phases — positive, neutral and negative — which influence the amount of rainfall on the eastern side of Australia especially. Essentially positive SAM in summer = more rain, and negative SAM in summer = less rain. These weather patterns tend to stick around for a couple of weeks at a time but apparently, this windy binch is set to hang around in its positive state for most of spring.
