I'd definitely recommend the journal Nature, it's a bit hit and miss with geography related articles, but they're excellent at covering natural disasters from an academic point of view. There's also Nature Geoscience and Nature Climate Change which have a greater link to geography. They're approximately £10 per issue or £79 for a student subscription, and are published on a weekly basis.
El Niño by Madeleine Nash is supposed to be very good. I'm personally more of a human geographer, but have a secret obsession with meteorology. I'm currently reading The Bottom Billion by Paul Collier, and my next reads are going to be 10 Billion and The 32 Stops by Danny Dorling.
I had an entire Amazon Wish List FULL of physical geography which I've been building up for the past 18 months but it's somehow been deleted. If I get the problem sorted, I'll post a link to it on here for you to have a look through.
