AbstractMonthly tropical sea surface temperature (SST) data are used as predictors to make statistical forecasts of cold season (November–March) precipitation and temperature for the contiguous United States. Through the use of the combined-lead sea surface temperature (CLSST) model, predictive information is discovered not just in recent SSTs but also from SSTs up to 18 months prior. We find that CLSST cold season forecast anomaly correlation skill is higher than that of the North American Multimodel Ensemble (NMME) and the SEAS5 model from the European Centre for Medium-Range Weather Forecasts (ECMWF) when averaged over the United States for both precipitation and 2-m air temperature. The precipitation forecast skill obtained by CLSST in parts of the Intermountain West is of particular interest because of its implications for water resources. In those regions, CLSST dramatically improves the skill over that of the dynamical model ensembles, which can be attributed to a robust statistical response of precipitation in this region to SST anomalies from the previous year in the tropical Pacific.

The relationship between the increase of the sea surface temperature observed off the Galician coast and the appearance of a tropical poikilotherm species Argonauta argo in these coasts is discussed. This is the first record of Argonautaargo in the north-west Iberian Peninsula. A female of this species was captured alive near the surface at dusk on 22 December 2000 in the Ria de Aldán (42°15′N–08°48′W). The specimen, a mature female of 70 mm mantle length and 96 mm shell diameter, died 36 hours after introduction in the tank.

Trend significance is evaluated and periodicities are revealed for time series of the sea surface temperature in the North-West Pacific. The dominant periods are selected using Fourier method under the assumption of linear trend existing over sufficiently large fluctuations. On the background of rapid warming in the 1983-2014, increasing fluctuations of summer SST were observed, with 7-year cycle domination, which were gradually shifted to August-September. Patterns of atmospheric circulation preceding to events of extreme thermal regime in summer are identified using the method of interval recognition: the extreme warm thermal regimes are formed mainly by subtropical anticyclones having a tendency to strengthen, and the extreme cold regimes are conditioned by strengthening of summer monsoon in its first stage.
