Extreme cold can prevent aircraft from operating, and could maroon the team at the station during the total darkness and bitter temperatures of austral winter.

Using information from stations operated by certified observers for which complete weeks of data were available the researchers calculated the difference between the highest temperature recorded during the day and the lowest recorded at night, the so - called diurnal temperature range (DTR).

Callas estimated that the temperatures Spirit will experience during winter, reaching down below — 40 degrees Celsius, would approach the boundaries of the rover's operating specs.

But such vacuum chambers are expensive to build and complicated to operate (requiring monitoring of pressure, temperature, current, voltage, time and other factors during the process of making the thin film).

Electrical shorts are not uncommon during the process of ramping up the LHC, but because the machine is already cooled down to its very low operating temperature, fixing the problem is now more difficult.

The engine operates in SPCCI mode the majority of the time, can switch into an ultra-lean burn mode during low revs and low load cruising (which, because of controlled, lower combustion temperatures, doesn't produce high levels of NOx like previous lean burn engines), and graduates to regular spark ignition under high load and high revs.

One problem with this type of battery is that it only operates efficiently in a narrow temperature range, so energy has to be expended to keep its temperature constant, and while the battery's capacity is equivalent to 53kWh it takes 70kWh to charge thanks to energy losses (as heat) during the charging process.

Engine cooling is prevented during the initial stages of a cold start so that the engine reaches its optimum operating temperature faster.

An electromagnetic clutch decouples the water pump pulley during engine warm - up, enabling normal operating temperature to be reached more quickly while reducing engine load and fuel consumption.

In addition, the 22 kW oil to water heat exchanger, packaged at the core of the engine, transfers heat from the coolant to the lubricating oil during warm up, bringing the oil up to operating temperature 14 percent faster than the previous cooling system.

Perhaps a change in instrument during the 1916 - 1984 time - period occurred that would affect this urbanization effect; I can't imagine the same instrument has been operating since 1916 and I would suspect the instruments have been better designed to deal with heating up from solar exposure so they would probably record cooler temperatures than the older instruments.

As for equilibrium, the system is never at equilibrium, but the incoming energy level is fairly constant, so the system should remain within a given temperature range, given the negative feedbacks operating during any excursions.

Orbital forcing changes associated with 5 deg C or greater variation but operating over 22,000 to 100,000 years, or diurnal variations of 5 to 10 C between mid-afternoon and pre-dawn temperatures are largely irrelevant to century long trends, such as the 0.8 C temperature rise during the past 100 years.

If the lowest temperature of the day is measured just after sunrise, and the highest temperature is measured in the afternoon, then both temperatures are measured during active operating times for commercial airports.

However, for radiosonde observations, which are irregularly spaced with large gaps over the oceans (Figure 2.6), global - mean temperature is estimated on the basis of those stations operating during the season in question.

Energy flux is perfectly fine for GCM models which operate on energy transfer rates but these models can not have their output converted to temperature values because temperature requires a time factor during which the energy flux was operating and no such time factor is available.

And in the summer if such a house is wisely operated (closing windows during the day, for example), it should maintain temperatures significantly cooler than outdoors.

With respect to claim number one that during the winters of 2014 and 2015 there were extremely cold temperatures that the farmer has «never seen before», we can check the claim by looking at the count of number of days below 0 F. Unfortunately the Fredonia monitoring site stopped operating in 2011 so I used the nearby Buffalo airport site.
