In the Northwest, the coldest days are near December 31st. Why is there a difference in the lag-time between these two locations? I thought perhaps it could be a result of snow cover that could reflect much of the sun's energy. However, in Winthrop, where there is a high probability of snow from December into March, the coldest day of the year is also near December 31st. It is even more puzzling after I've learned about the upper air pattern. Do you have an explanation?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-3956342959147720472014-03-21T19:07:47.479-07:002014-03-21T19:07:47.479-07:00Appreciate the illustration, "mini" less...Appreciate the illustration, "mini" lesson, Professor.richard583https://www.blogger.com/profile/00415086002282750839noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-40572991084342114142014-03-21T18:55:05.915-07:002014-03-21T18:55:05.915-07:00Why is there such a huge seasonal disconnect betwe...Why is there such a huge seasonal disconnect between the cold surface temps and the cold 850mb temps? Nearly 2 1/2 months, and by mid-March the average high temps at the surface are 8-15 degrees F above their early January levels.<br /><br />How do the 850-vs-surface seasonal temperature curves of OTHER midlatitude climates compare to ours? Is there a general categorical difference between oceanic and continental seasonal temperature curves?Karl Bonnerhttps://www.blogger.com/profile/10418986386619849310noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-87239210252026121102014-03-21T09:10:19.817-07:002014-03-21T09:10:19.817-07:00> The air has a substantial

It has more<br />> heat capacity <br /><br />That changes dramatically with humidity, right?<br /><br />So upper level air that's lost its moisture because the water froze out is more transparent to outgoing infrared and so it can stay cool by losing heat to space, compared to moist air in which infrared is absorbed by water vapor and heat passed around to surrounding molecules by collision? <br /><br />Correction appreciated, this is hard stuff to follow.Hank Robertshttps://www.blogger.com/profile/07521410755553979665noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-74201972737065001442014-03-21T07:41:08.159-07:002014-03-21T07:41:08.159-07:00Great post, Cliff!

Fortunately, no supercells like they get in the Midwest (I am thankful for dewpoints under 60!) NateLMPhttps://www.blogger.com/profile/17018906593548986591noreply@blogger.com
