A rhumbline is a navigational convenience so that an angle of travel can always intersect lines of longitude at the same angle, making navigation by compass easier, though it isn't necessarily the true "straight" line path.<br />Coincidentally, rhumblines appear straight in the Mercator projection, (which is used in this map for better or worse) so the tracks you see in this map are actually rhumblines. It's why the Mercator projection was so popular for 15th century navigators ("we'll take the winding way home but at least we can plot it on a map").<br />Were I more intelligent, according to "OneoldDude" I'd have used great circle paths. But I'm not and I didn't.

It might be more accurate to draw a rhumbline between the two points instead of a straighth line in 2D, but without more points to describe the actual path, the rhumbline would still only be a "best guess"!Bassman50https://www.blogger.com/profile/10936267454764129843noreply@blogger.comtag:blogger.com,1999:blog-7944244193491078105.post-36923642926621406532012-08-01T13:48:27.992-04:002012-08-01T13:48:27.992-04:00Agreed.

It is not impossible for a weaker tornado to form in this region, nor do the mountains somehow protect this region from tornadoes, they are just not as common of an even here as they are in the great plains and the deep south. Most of the tornadoes that form in this region are weaker and have shorter paths, this is in part because of the many factors effecting tornado genesis are not present or are much weaker in the region (instability of rising air, mid level wind sheer, and many other factors too complicated to explain) also many of the tornadoes in this region are produced from storms once associated with a hurricane or tropical storm. I hope this answers your questions.OKWeatherGirlhttps://www.blogger.com/profile/07517671391114820720noreply@blogger.comtag:blogger.com,1999:blog-7944244193491078105.post-34057660941988505702012-07-18T09:18:10.931-04:002012-07-18T09:18:10.931-04:00I'd like to ask the same question as lakes451....I'd like to ask the same question as lakes451.
