Figure 5.33. Mean anomalies of winter and summer T. in 10 stations representing climatic regions and sub-regions over the period 1951-1990 (or 1967—1990 for the Russian stations).

S p r i n g. In the spring, circulation types are characterised by a far greater uniformity of influence than in the winter. The anomalies of T., on the other hand, are high. They are slightly lower than in the winter in ATLR and in the remaining area of the Arctic they are higher than in the winter. Negative anomalies bring the following types: I, VI, VIII, IX, XIV, and XV; this applies to almost all of the Arctic, except for certain areas located mostly in ATLR. The warmest types, on the other hand, are (again with the exception of certain areas of ATLR) types III-V, VII, and XI-XIII. By far the lowest T. throughout most of the Arctic coincide with type VI (with anomalies oscillating between -0.6°C and -6.9°C) whereas the highest T. coincide with type XI (with anomalies ranging between 0.4°C and 4.8°C). A marked uniformity in the influence of circulation types may be observed throughout the Arctic except for ATLR (Table 5.20b).

Table 5.20b. Mean anomalies of T. in spring (in °C) in the Arctic for each type (I, II,.., XVI), group (A, B, W, G, D, and K), and macrotype (W, C, and E) of circulation over the period 1951-1990
