Interestingly counter-intuitive is the air conditioner effect in Paris
on nighttime temperatures.
Hot nights make for bad sleep, according to a study combining responses to a U.S. Centers for Disease Control and Prevention sleep survey of 765,000 U.S. residents from 2002 to 2011 with data
on nighttime temperatures during that period.
One meteorological reason that I wonder about a poor correlation is that I expect the effect of wind
on nighttime temperature to be greater than the 1C Parker shows.

This is based
on personal experience with my (much older) Civic with a non-new battery and similar driving patterns in the winter with typical
nighttime temperatures around 28 - 34 F.
The morning LOW
temperature in Florida
on 5/17/2016 (the date the above satellite photo was captured) tied all time record of 78 degrees (again, 78 degrees was the
nighttime LOW
temperature).

On dry savannas in Africa the surface temperature of clear climate during daytime can reach about 50 C, but during nighttime can cool down until about zero C. However, CO2 content in atmosphere during all the time is the same, which proves that the carbon dioxide as greenhouse gas in atmosphere has no distinguishable influence on climate temperatur

These issues, which are either not recognized at all in the assessments or are understated, include: - the identification of a warm bias in
nighttime minimum
temperatures - poor siting of the instrumentation to measure
temperatures - the influence of trends in surface air water vapor content
on temperature trends - the quantification of uncertainties in the homogenization of surface
temperature data, and the influence of land use / land cover change
on surface
temperature trends.
NOAA Coral Reef Watch (CRW) thermal stress products used in this study were based
on nighttime - only Advanced Very High Resolution Radiometer (AVHRR) sea surface
temperature (SST) data from sensors aboard operational NOAA Polar - Orbiting Environmental Satellites (POES), produced in near - real - time at 0.5 - degree (50 - km) spatial resolution.
On the moon, where there is no atmosphere, the daytime
temperature can be extremely hot and the
nighttime temperature extremely cold.
With the sun and the «greenhouse gases», but without water, the average
temperature on earth would be of - 11 °C (resulting from a daytime mean
temperature of approximately +135 °C and a
nighttime temperature of approximately - 175 °C).
It would probably be equal to the typical daytime minus
nighttime temperature difference at that time of year and location
on the Earth.
Bottom line is if there were no greenhouse gases in the atmosphere like
on the moon, daytime high
temperatures at the equator in the spring and fall would exceed the boiling point of water and of course
nighttime temperatures would plunge far below freezing.
In fact, «Conventionally, UHI was detected from
nighttime World Meteorological Organization (WMO) 2 - metre surface air
temperature records» (http://climate.gsfc.nasa.gov/publications/fulltext/Jin.BAMS.pdf, which also has many useful UHI references, and information
on how UHI is being incorporated into climate models).
On cold nights, turbulence stirs the lower atmosphere and keeps
nighttime temperatures around the crops warmer, potentially warding off early fall frosts and extending the growing season.
Regarding crop yield declines for rice, previously research
on rice grown in Asia has shown that for every 1 °C increase in minimum
nighttime temperatures crop yields declined 10 %.
Given the strong damping effect of clouds
on the daytime maximum
temperature and DTR, the well - established worldwide asymmetric trends of the daytime and
nighttime temperatures and the DTR decreases during the last 4â??
The net effects of clouds
on the
nighttime minimum
temperature is small except in the winter high latitudes where the greenhouse warming effect of clouds exceeds their solar cooling effect.
Postscript: Not exactly
on topic, but one thing that is never, ever mentioned in the press but is generally true about
temperature trends — almost all of the warming we have seen is in
nighttime temperatures, rather than day time.
The average
temperature is what is being focused
on by most scientists, but I agree with Nasif it needs to be looked
on with what happens real - time while it is net absorbing daytime and net emitting
nighttime.
I am uncertain how to interpret the research about the effect of increased
nighttime temperature on wheat yield.
