Several reports about strong positive temperature anomalies exist, for instance from Toscana and Veneto.
This found problems when attempting to demonstrate the statistical significance of apparent temperature anomalies.
A temperature anomaly is measured against a reference value or long-term average.
Though lying within the Arctic Circle, Lofoten has one of the world's largest higher temperature anomalies relative to its high latitude.
Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values.
In this type of atmosphere, high and low pressure areas are centers of warm and cold temperature anomalies.
However, in areas where deep permafrost developed during the Pleistocene a low temperature anomaly can be observed that persists down to several hundred metres.
Though lying within the Arctic Circle, the archipelago experiences one of the world's largest elevated temperature anomalies relative to its high latitude.
Increased rainfall relative to normal is typically associated with negative temperature anomalies over these tropical land areas.
Building envelope thermography involves using an infrared camera to view temperature anomalies on the interior and exterior surfaces of the structure.
