what is common between foehn and chinook winds
Chinook wind A strong föhn wind can make snow one foot (30 cm) deep almost vanish in one day[citation needed]. The snow partly melts and partly evaporates in the dry wind. Chinook winds have been observed to raise winter temperature, often from below −20 °C (−4 °F) to as high as 10–20 °C (50–68 °F) for a few hours or days, then temperatures plummet to their base levels. The greatest recorded temperature change in 24 hours was caused by Chinook winds on 15 January 1972, in Loma, Montana; the temperature rose from −48 to +9 °C (−54 to +49 °F).[3]
The Winds of Winter On January 10, 2017, Martin announced on his blog in a response to a comment that he believed that The Winds of Winter will be released "this year", referring to 2017. However, he also noted that he believed the same thing would occur the previous year.[6][7][8] He confirmed on his blog that he was still working on The Winds of Winter as of July 22, 2017, being "still months away" from finishing the book. He also indicated that it may not be published until 2018 or later.[62]
