Analysis of 7 to 8-year oscillations revealed a contrast in their phases in the subtropical and sub-polar cycles of the northern Atlantic. Three prevailing periods have been recorded for interannual variability (2-6 years) 24-30 months, 40 months, and 60-65 months. The first of these periodicities is the well-known quasi-2-year component of ENSO which manifests itself most strongly in the tropics of the western sector of the Pacific, with anomalies (of a constant sign) propagating along the western coast of North and South America (in other oceans this variability is negligibly small). 

The main goals of these programs are resolution of two problems. 

Recently close attention has been given to assessment of climate in Siberia and the Far East as regions adjacent to the Arctic. Flere a 0.5°-0.9°C increase of temperature in the last decade was observed, the trends of average temperatures increasing from north to south. Precipitation was redistributed, with an increase in winter and a negligible decrease in some regions in summer. For instance, in the Amur River basin over the last 30 years precipitation in the cold period of the year increased by 35%, and annual precipitation increased by 12.3%.

Components in which water temperature changes abruptly with distance, such as heat exchangers, tend to accumulate precipitates. Heater surfaces also accumulate precipitates if the dissolved species have inverse temperature solubilities. Systems in which pH excursions are frequent may accumulate deposits due to precipitation processes. Plenum regions, such as heat exchanger headboxes, tend to collect deposits. 

Importantly, all biological procedures are operating at a temperature of 310 Kelvin, not at 0 Kelvin as the potential energy is calculated by the force fields. The kinetic energy must also be considered. Molecules and proteins at room temperature change the conformation at least at the surface and in loop region. Molecular dynamics simulation (MD) is an approach to tackle these kinetic and stability problems. 

On the basis of results from GCM (Eig. 3) the AR4 summarizes the projected changes for the Mediterranean region (Table 1, regarding temperature changes Table 2 for precipitation), the moderate emission scenario AIB having been... 

The temperature sensitivity of the saturation velocity, Vsat, used in Eq. (4.5) to describe the effect of the lateral field, is additionally considered. The saturation velocity is moderately affected by temperature changes however, when the temperature largely deviates from Tnom. there is a strong effect on the saturation region characteristics of the transistor. The temperature dependence of the saturation velocity is taken into account using the temperature coefficient, AT, [BSIM 3.v3,129] ...
