A joint post with Steve Hempell
Steve Hempell has been using v1.2.1 of the code to analyse temperature history in sub-regions of Canada, and in global latitude bands. Here are his results for the latitude behaviour in 20 deg bands. Steve (his blog handle here) has also made a finer resolution, which we will present in a future post.The results confirm the high recent uptrend in the Arctic, with relatively small trends in the SH. Remember, though that these are land stations only, and do not give a good picture of the whole SH.
Table of trends
| Trend | Tropics | NExTropics | NMidLat | NHighLat | SExTropics | SMidLat | SHighLat |
| C/Decade | 20N to 20S | 40N to 20N | 60N to 40 N | Above 60N | 20S to 40S | 40S to 60S | Below 60S |
| 1900 - 2009 | 0.0578 | 0.0667 | 0.105 | 0.1015 | 0.0511 | 0.0409 | 0.190 |

ReplyDeleteAre you going to post US results
Steve, there are US results at the previous post (first set).
ReplyDeleteIt might be useful to make a graph in this form: http://i81.photobucket.com/albums/j237/hausfath/Graph.png
ReplyDeleteZeke,
ReplyDeleteYes, I'll do something like that next post. Currently I haven't routinely printed trend se - I've been citing trends as a measure of agreement with other calcs, not for their absolute value. The next version will do it.
