Purple haze all in my brain... well, with all due apologies to Jimi Hendrix, it's actually been more of a translucent and velvet vog that hovered over Oahu and other islands in recent weeks. And yes, the tradewinds do invariably come back and let us once again gaze upon majestic mountains and scenic city views.
But just think about how people in Los Angeles or Beijing or Mexico City or Denver are immune to these types of hazy days. For in those cities, bad air is not an anomaly, it's the norm. And to make matters worse, the particles in the air in those cities and countless others, is a lot worse to breathe in and breathe out than the air we deal with when we have volcanic emissions.
