Talk:Helm Wind

message: A photo to illustrate the dramatic cloud formation of the Helm Bar would add to the value of this article. I would put a photo of its "Mallerstang little brother" here, but one of the Bar over Cross Fell should have priority. (The photo taken from Appleby would be fine - and if this was taken by the anonymous 81.158.33.108 who added the link, perhaps he/she might think of uploading the image)?

message: The Cross fell article links here, but has an extensive discussion of the wind - which I have moved here:
The Helm Wind is a local phenomenon. An east wind causes air to rise slowly to the summit of the ridge and cool as it does so. At the summit, the dense, cool air drops rapidly down the steep western slope (causing the Helm Wind) and forces warmer ambient air to rise. Moisture in the ambient air condenses to form the Helm Bar – a stationary handle of thin cloud running along and outwards from the edge of the summit (see Picture Gallery below). The Helm Wind can be very strong where it is channelled down gullies in the side of the escarpment. It is experienced particularly in the villages of Milburn and Kirkland.The Helm Bar: an account A Helm Wind also occurs at the head of the Eden Valley, in Mallerstang. A similar feature can be found around Table Mountain near Cape Town, South Africa, where the local equivalent of the Helm Bar is known as the Table Cloth.

replies: text: It looks like you have done some good work in pruning "Cross Fell". If you are happy about the description of Helm wind that had been there, and which you have moved to this talk page, I would encourage you to incorporate it (or an edited form) into this article.

message: After further reflection (see section above) I don't think that the Helm Wind can be properly classed as a foehn, so have edited the article accordingly. The ridge over which the wind flows isn't high enough, and the air (coming from the east) is rarely moist enough, for the uplift to cause substantial precipitation over the high ground, something that's necessary for the foehn effect to occur. I'm not aware of any measurements showing an increase in temperature on the lee side compared to somewhere at a similar height on the upwind side. (Unlike in some coastal places in north Wales, where a foehn effect of a few degrees has been shown occasionally to occur when a southerly blows over Snowdonia.) However if there's a meteorology book or paper that can be cited to say that I'm wrong, then I will of course withdraw my objection. JH (talk page) 19:17, 8 November 2011 (UTC)
thread_title:  Not a foehn 

message: I'm not sure that the description of the Helm Bar as "a line of clouds over the fells" is correct. The article below (cited in this article) describes the Helm Bar as the long, narrow cloud that forms over the valley bottom. The parallel cloud that forms over the fells is the Helm Cloud:
you are 100% correct. I have attempted to get it corrected but person who wrote original page wont accept this as fact. Or admit his page is wrong.
