"Nighttime temperatures" refers to the measurement of how hot or cold it is during the night.
Full definition
There has also been a dramatic increase
in nighttime temperatures in the US, reducing the number of critically important relief windows during heat waves.
And while that high ranking was fueled in part by a major heat wave out West, a big factor was the very
warm nighttime temperatures across a large swath of the country.
After an 11 - year inquiry, a group of Asian and American researchers found a 10 percent drop in rice - crop yields for every increase in
nighttime temperatures of 1.8 degrees Fahrenheit.
Overall, the results showed if
nighttime temperature increased 1.8 °F ahrenheit above normal across the United States for a month, people would report 9 million more nights of insufficient sleep during that period.
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 %.
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.
During the winter, temperatures in Vallarta are in the low to mid 80's during the day
with nighttime temperatures ranging from the 60 - 70 ° F. Summertime (June to October) is Vallarta's rainy season with temperatures ranging from the mid 80's to low 90's.
Scientists sifting for trends in record high and low temperatures across the United States have found more evidence of long - term warming of the climate, with the biggest shift coming through a reduction in record
low nighttime temperatures.
The researchers studied these CDC reports of inadequate sleep levels from 765,000 individuals across the country alongside city - level
nighttime temperature data from 2002 to 2011.
«Mars is a very difficult environment for power systems, with less sunlight than Earth or the moon, very
cold nighttime temperatures, very interesting dust storms that can last weeks and months that engulf the entire planet,» said Steve Jurczyk, associate administrator of NASA's Space Technology Mission Directorate.
The researchers have found that winter - grown canola is particularly affected
by nighttime temperature rises during the flowering and seed - forming stages.
The investigation of self - reported sleep patterns and
nighttime temperatures across the United States is one of the first studies to provide evidence that rising temperatures, driven by climate change, could affect human sleep.
With
average nighttime temperatures up 1.8 degrees F at the institute's farm in the Philippines from 1979 to 2003, average yields were down 10 percent.
And sap can only be harvested in the spring when
nighttime temperatures don't dip below the mid 20s and daytime highs don't top about 45.»
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.
Consequently, the difference between day and night is more extreme with daytime temperatures getting up to around 118 °C and
nighttime temperatures falling below -168 °C.
The daytime and
nighttime temperature fluctuations and changing pressure acts as a pump that pushes sap out through the tap and into the lines that drain the sap to the sugarhouse where syrup is made.
For the sand flies, the decisive factor was microclimate — temperature,
especially nighttime temperature, and humidity in the cracks in adobe walls where the insects live.
According to a 2013 report by Climate Central, nationwide nighttime winter temperatures since 1970 have risen about 30 percent faster than
nighttime temperatures over the entire year.
«Those minimum
nighttime temperatures reflect only the temperature of a shallow layer of air near the surface and not temperatures in the deep layer of the atmosphere.»
The distribution of the warming trends were, however, not geographically uniform with many coastal locations and those near «large water bodies» indicating significant opposite trends, especially to the north of 5 degrees S. Locations north of 5 degrees S indicated more organized decreasing or increasing diurnal trend in the daytime /
nighttime temperature patterns.»
That explains why the desert is known for rapid temperature swings — hot days and cold nights — while coastal areas are noted for their moderate climates, with day and
nighttime temperatures closer together, he said.
Urban areas are particularly vulnerable, because dark asphalt and rooftops absorb more solar radiation than natural landscapes,
raising nighttime temperatures by as much as five degrees, according to NASA studies.
