Because of the record cold in the mesosphere noctilucent clouds are distributed farther

On the border with outer space is always very cold, but this year in the mesosphere recorded a record low temperature. Such conditions led to the spread of noctilucent clouds. June 9 they came near the southern border between Utah and Idaho. Kenneth Zia saw them over the Northern horizon from Logan, Utah, then called up his brother-in-law in Boise, Idaho. Brother-in-law went outside and saw noctilucent clouds.

Noctilucent clouds stand out among the rest not only for its unusual appearance, they are the most high-rise on the Earth. These clouds are formed at the border with a space at an altitude of over 80 km Summer jet of water vapor rise into the mesosphere, and the water kristallizuetsya around meteoric particles.

Last summer noctilucent clouds spread far to the South (in the US — to Los Angeles), setting records of observations at lower latitudes. I will repeat something similar this year? Conditions are formed in such a way that it becomes quite likely.
