Sentences with phrase «mean annual temperature occurred»

Given the fact that the latitudinal position of successful post-fire regeneration of lichen - spruce woodlands is situated approximately 1.5 ° south of the Boniface area (Payette et al. 1989a, b), as a rule of thumb it is probable that a drop of at least 1 °C in mean annual temperature occurred after 900 cal.

What matters is that the higher mean annual temperature occurs where there are fewer clouds.

... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and global mean temperature... Polar amplification occurs if the magnitude of zonally averaged surface temperature change at high latitudes exceeds the globally averaged temperature change, in response to climate forcings and on time scales greater than the annual cycle.

Scientists use permafrost temperature, measured at a depth where seasonal variations cease to occur, as an indicator of long - term change and to represent the mean annual ground temperature.
