Vombatsi: Ja, det er desværre tonen for nogles vedkommende.
Jeg beskrev mine egne erfaringer, men her er nogle "mere tekniske" svar:
Kort oversættelse, derefter den fulde engelske tekst.
What is the warmest time of the day?
Generelt kort før solnedgang, da solen da har haft længst tid til at opvarme jorden.
Usually it is just prior to sunset, when the sun has had the most time to shine on the land and warm it.
I modsætning til den almindelige opfattelse, er den varmeste tid på dagen ikke, 12 frokost.Den varmeste tid er mellem 3:00 og 6:00, lænende mod 6:00.
Despite popular belief, the warmest time of the day isn’t high noon. The warmest time of the day is between 3:00 and 6:00 p.m. and the high is usually recorded between 5:30 and 6:00 p.m. Of course how warm it gets is impacted by weather conditions and latitude.
What is the coldest time of the day?
Den koldeste tid er lige før solopgang.
Though some may believe the coldest time of the day is at midnight, or some time before the sun rises, this is generally not true. The coldest time of the day is usually just after the sun rises. However, there are a few times, especially in the winter, when the coldest time of the day may not be during this morning time period. Weather patterns can play a role in determining when low temperatures hit during the day.
To fully understand why the coldest time of the day is just after sunrise, it is important to understand how the Earth receives and loses heat. The planet is constantly receiving radiant heat from space and returning it to space. The vast majority of the heat the Earth receives comes from the sun. During the day, heat is gained and during the night it is lost. However, just because it is night at your location does not mean the entire Earth is losing heat. One side is losing heat, but the side facing the sun is gaining heat.
As the sun rises, the portion of the Earth that is just beginning to receive the sun's rays is still in the process of losing heat. As with any property governed by inertia, it takes a little time to reverse this trend. Meteorologist David Cook at the Argonne National Laboratory explains "Because the sun is so low to the horizon at sunrise, most of the energy is absorbed by the distant atmosphere."
However, weather changes from day to day and the coldest time of the day may not always be during the time right after dawn. In some cases, a cold front could pass through a location, leading to cold temperatures at any point during the day, if the front is powerful enough. If this happens, the coldest time of the day will likely be in the hours after the front passes through.
While your part of the earth has the greatest amount of sun exposure during the early afternoon hours it takes time to heat the surface of the earth. The delay between maximum sun exposure and the warmest time of the day is called thermal response. How long it takes to heat up your little spot on the planet depends on latitude and the time of year. Usually it takes about three to four hours.
