Sentences with phrase «nighttime temperature increased»

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.

Not exact matches

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.

Record - breaking nighttime temperatures have already been increasing across 90 percent of the studied areas, the research suggests, and these records may increase by at least fivefold across half of Europe and a quarter of East Asia.

All of these important steps are limited when the temperature increases, including during nighttime.

That trend in increasing nighttime low temperatures is expected to continue for the entire

In many cases, nighttime low temperatures are increasing more rapidly than daytime high temperatures.

Global climate models have successfully predicted the rise in temperature as greenhouse gases increased, the cooling of the stratosphere as the troposphere warmed, polar amplification due the ice - albedo effect and other effects, greater increase in nighttime than in daytime temperatures, and the magnitude and duration of the cooling from the eruption of Mount Pinatubo.

In cities like Phoenix with bad UHI problems, the mean temperature has increased because nighttime temperatures don't cool much any more.

This unique response of RSM to extra soil moisture provided by irrigation is consistent with Christy et al. (2006)'s observational study that found increased nighttime minimum temperature in California Central Valley during the last century.

Our paper shows that in such circumstances where nighttime cooling is reduced systematically over time, i.e., under trends of greater atmospheric greenhouse gases or an increase in cloudiness, the resulting effect will be to increase minimum temperatures from what they would have been absent the reduced nighttime cooling.

Christy mentions an increase in nighttime low temperatures by 5.5 F between 1910 and 2003.

Prolonged periods of high temperatures and the persistence of high nighttime temperatures have increased in many locations (especially in urban areas) over the past half century.

During extreme heat events, nighttime temperatures in the region's big cities are generally several degrees higher28 than surrounding regions, leading to increased heat - related death among those less able to recover from the heat of the day.36 Since the hottest days in the Northeast are often associated with high concentrations of ground - level ozone and other pollutants, 37 the combination of heat stress and poor air quality can pose a major health risk to vulnerable groups: young children, the elderly, and those with pre-existing health conditions including asthma.29 Vulnerability is further increased as key infrastructure, including electricity for potentially life - saving air conditioning, is more likely to fail precisely when it is most needed — when demand exceeds available supply.

However, over this period, the nighttime minimum temperature increased.

Clouds then are highly nonlinear temperature regulators — both increasing daytime albedo and increasing nighttime greenhouse trapping.

I went to great length trying to explain to you that when you observe increasing or decreasing delta in daytime high temperature and nighttime low temperature it is almost certainly due to concommitant trend in absolute humidity.

In recent decades the ITCZ has been migrating north moving it farther away from Easter Island and as that distance increases absolute humidity over Easter Island will necessarily decrease which necessarily means in increasing temperature delta between daytime high and nighttime low.

There has also been a dramatic increase in nighttime temperatures in the US, reducing the number of critically important relief windows during heat waves.

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 %.

If they are the cause of global warming, average nighttime temperatures should increase more than daytime ones — reducing the total daily temperature swing.

``... most of the warming which has occurred in these regions over the past four decades can be attributed to an increase of mean minimum (mostly nighttime) temperatures....

That study started with the optimal nighttime temperature, and then tested the impact of increasing that temperature.

I am uncertain how to interpret the research about the effect of increased nighttime temperature on wheat yield.

A low cloud cover increases the sky emittance and hence «back» radiation.The surface energy balance then shows that the surface temperature increases and the convection heat loss from the ocean decreases: thus the nighttime subsurface ocean temperature does not decrease as much compared to that for a clear sky.
