Yes, heat flow out of the atmosphere changes during a day due to variations in solar radiation, cloud cover, and air temperature. At night, heat loss is generally higher as there is no incoming solar radiation, while during the day, heat gain from the sun can offset some of this loss. Temperature differences between day and night contribute to this fluctuation in heat flow.
== == "Plat" is the French word for "dish" / "course"; "Jour" means "day". "plat de jour" is the "dish of the day", but sometimes it is used in the sense of "menu of the day", which can include more than one dish, i.e. entrée + main dish + dessert
It's Plat du jour. :)
No, land breeze occurs at night when the land cools down faster than the sea, causing the air over the land to sink and flow towards the sea. During the day, sea breezes are more common as the land heats up faster than the sea, causing the air to rise over the land and flow towards the sea.
During the day, land heats up faster than water causing air to rise over land and cooler air to flow in from the sea, creating daytime sea breezes. At night, land cools down faster than water, causing air to flow from land towards the sea, creating nighttime land breezes.
This is called upslope winds or upslope flow. As the sun heats the mountain slopes during the day, the air near the surface is also heated and rises upslope creating the flow. As the air rises, it cools and condenses, leading to cloud formation and potentially precipitation on the windward side of the mountain.
the cool air pushes the warm air
Mountain breezes typically form during the night. As the sun sets, the air in the valley cools more quickly than the air on the mountain, creating a temperature difference. This temperature difference causes the air to flow from the mountain down into the valley, creating a mountain breeze.
cold temperatures make the sap work its way up the tree, so during the day, when the temperature is warmer, the sap can flow down
A sea breeze would form when cool air moves from an ocean onto dry land. The air over the ocean is cooler than the air over the land during the day, causing the cool sea breeze to move inland. This flow is typically strongest during the day when the temperature difference between the land and sea is greatest.
its colder at night than it is during the day, so it feels colder at night.
on a French restaurant menu, the specialty of the day is called "le plat du jour"
