> One important player is the Madden-Julian oscillation (MJO), a disturbance of clouds and rain in the tropics that circles the globe in roughly 30 to 60 days.
This puts a name to something I was observing in Apple Weather these past few months (I’ve been spending some time in there just observing weather, partly due to Dark Sky shutting down and partly due to the onslaught of storms that hit us). If you spend enough time observing a radar map of weather around the globe, what becomes apparent is the source of a lot of water. A lot of the “atmospheric rivers” that hit California appeared to have their origins southeast of the Philippines. Actually there’s a lot of crazy weather going on between Northern Australia and Southern China.
You’ll also see this nearly contiguous belt of rain just circumnavigating along the Equator from West to East. Notable stops along this route if you don’t know your Equatorial geography include Tanzania where Mt. Kilimanjaro is, Lake Victoria which is the source of the Nile, most of the World’s Rainforests, the Andes which are functionally this enormous moisture trap that turns most of eastern South America into this giant drainage basin, and interesting enough that little spot southeast of the Philippines that seemed to be continuously feeding the storms that hit the West Coast in North America.
This is apparently Madden-Julian oscillation and taking a quick glance at the Wikipedia page, that appears to be exactly what I was looking at. If I were looking in the Summer, I might have seen a connection to the monsoon season in India because it is apparently linked to those too via its oscillations. This is neat. This is the best article to hit Hacker News today since it taught me something new.
the dry, temperate weather that has historically made homelessness in San Diego County relatively tolerable may be a thing of the past. Recent weather in California has been generally both hotter and wetter. Some studies suggest that hotter, much wetter weather may be the new norm for California thanks to global warming.
From an old blog post of mine, written November 2017.
California has about one quarter of America's homeless population, likely due in part to the history of dry, temperate weather in large parts of California. If Cali is going to generally trend hotter and wetter, we need to more urgently than ever find solutions for getting people into permanent housing and keeping them there.
California has 1/8th the US population, so it's double on a per-capita adjusted basis. IIRC if you also adjust for housing prices (which, perhaps unsurprisingly is correlated with homeless population) the adjusted rate is even closer. To the degree that weather affects housing costs (maybe not in the bay area, but SoCal and parts of the central coast this has an effect), the worsening weather might improve the homeless situation.
