Does anyone know where I could find the general trends of winds around the world? Nothing specific to the current weather, but just some rules of thumb. For example, winds for JFK-LHR result in a 6 hour flight, and the other direction is 7+ hours.
Well we all know weather changes all the time, even trends. Basically, the most "general" trend you can define is that just about everything flows from west to east. Here's a site for some anaysises: http://squall.sfsu.edu/crws/jetstream.html
