James Deane sent me a nice series of pictures taken on the last day of 2010. The images show a cloud inversion on the Isle of Jura. To explain what a cloud inversion is I found a quote from Wikipedia: "Under certain conditions, the normal vertical temperature gradient is inverted such that the air is colder near the surface of the Earth. This can occur when, for example, a warmer, less dense air mass moves over a cooler, denser air mass. This type of inversion occurs in the vicinity of warm fronts. With sufficient humidity in the cooler layer, fog is typically present below the inversion cap." This is most likely the case on the images James sent me. What also surprised me was the fact that the snow on the Paps of Jura has completely disappeared. Thanks James for the nice pictures!
