Sentences with phrase «in thermometer screens»

Uncertainties due to changes in thermometer screens are poorly known but could be 0.1 °C globally in the 19th and early 20th centuries (Parker, 1994); they are not included here, but a preliminary analysis appears in Folland et al. (2001).

«It turns out that the thermometers were never in the jar recording the temperature rise presented in the split screen and the entire presentation was nothing but stagecraft and editing.»

At Tmax, for example, there has been a steady T rise as the sun moves higher in the sky, the rise helped by convection of air with hot packets in it surrounding the site, held back if frost has formed overnight, complicated if there is snow around and water phase change effects need consideration, hindered or lagged by the thermal inertia of the screen surrounding the thermometer as the screen heats up.

Station 9034 closed in 1992 and the Stevenson Screen thermometer was moved four kilometres north to establish the Perth Metro station in Mt Lawley (9225, elevation 24.9 m), with the 9034 historic record adjusted for baseline equivalence for both the Perth Metro and Perth Airport stations.

Most of the stations have changed from using liquid in glass thermometers (LiG) in Stevenson screens to electronic Minimum Maximum Temperature Systems (MMTS) or Automated Surface Observing Systems (ASOS).

Neither the max min thermometer nor the Stephenson screen were universally adopted until the 20th century and the manner in which thermometers were read and the time of observation issues were often complained about by the scientists of the day over a century ago.
