Water Levels in New York City

with 3 comments

update Monday; October 29, 2012 3:18pm (CDT) Eric Holthaus at the Wall Street Journal has a more in-depth analysis for the coming hours

I’ve been following the unfolding Sandy in the last couple of days. I’ve been relying of many online sources. Since I don’t have anything original to say, I decided to wait with a post here until things have settled down a bit.

However, I wanted to share this one chart of the water levels at “The Battery NY” (original available here. It shows observed (red dots) vs. modelled (pink and green) water levels. Note that the current water level is (slightly) higher than predicted. This has been true for the last couple of high tides, but those had smaller peaks.

The coming hours will be critical! There is a high tide coming up, coinciding with the landfall of Sandy. Additionally there’s a mid-latitude trough just east of the Great Lakes that pulls Sandy onto the North American continent. Additionally, as if that wasn’t enough, the North Atlantic Oscillation is in a negative phase, pulling Sandy towards the North-East. Decent summaries can be found here and here.

  1. I don’t leave many remarks, however i did some searching and wound up here Water Levels in New York City at planetwater. And I do have a couple of questions for you if you do not mind. Could it be just me or does it look like a few of the comments look like written by brain dead visitors? 😛 And, if you are posting at additional places, I’d like to keep up with anything fresh you have to post. Would you list of the complete urls of your social pages like your Facebook page, twitter feed, or linkedin profile?
