The process is not fully understood, but some of the more current thoughts are that the flu prefers and thrives better in the humidity of colder weather (drier absolute humidity) compared to humidity in other seasons. It is thought that it might be only the humidity level differences that link viral flu and cold infections to the fall and winter seasons, but, as has often been cited, perhaps there is also a component of the closer proximity of people to each other indoors in the cold weather which allows for easier direct transmission of the viruses. Scientific studies have ruled out a role of weather temperature differences. It is proven that you don't get colds from being cold.
Other reasons are sometimes given, for example, one thought is that it is the lowered amount of available sunlight in these seasons and shorter length of time periods that people are outside in the sun that result in lower Vitamin D (the "sunshine vitamin") levels. Deficiency of Vitamin D can impact the immune system negatively, but there is not consensus among the medical community on how much impact this actually may or may not have on infection rates.
Another factor that gets discussed is that there may be an effect from lowered amounts of sunlight, especially ultraviolet sunlight, available in those seasons which helps to de-activate the viruses.
You are correct that it is not the cold temperature that gives us colds, but rather the microorganisms that move from person to person during the "cold and flu season" that make us sick with the flu or a common cold.
When the temperature changes, a weather front or climate change is occurring. Therefore, using the temperature changes, one can determine what will happen in the near future.
Pressure drops when the temperature drops.
Thunderstorms are most likely to form during warm weather. In simple terms, the heat is their source of energy.
The common cold viral infection, bacterial infections of the respiratory tract, and influenza viral infections are the common illnesses in the winter. But, they are not caused bythe cold weather, they just happen at that time of year.The only "diseases" caused by cold weather are really only injury from exposure (like frostbite) or hypothermia-related disorders. See the related question below for more information about why these infections of viruses and bacteria tend to occur in winter.
It happen more quickley at warm temperature.
Extreme weather happens every where in the world when the weather gets bad.
Weather is caused by the atmosphere responding to uneven heating of the Earth by the sun. The uneven heating results in temperature differences. These are what are known as cold fronts, warm fronts and other phenomena.
this might happen if you do not wash propely
Yes, weather does happen in the stratosphere. While most weather happens in the troposphere, some does happen in the stratosphere. Most notably, the tops of severe thunderstorms may penetrate into the stratosphere.
They tend to prefer cool weather just like us. But if you happen to live in a tropical island, like me, always have water handy.
Infections happen in half the patients and often appear during the first week.
clear, dry weather
So they can know what will happen with the weather and, what to do.
The water cycle
Tsunamis can happen under any weather conditions as they are not weather-related.
A weather advisory is a warning for severe weather that is likely to happen in the next few hours.
We study weather so we know what is going to happen. If we didn't, we would get unexpected weather.
Hopefully, the rat has no diseases or infections, so nothing should happen.
The temperature drops about 10° per second. This couldn't actually happen. Also, Global Warming can lead to Global Cooling, but it can't happen as fast as in the movie.
Some people with HIV have a purulent infections. Most purulent infections happen in patients without HIV.
it is the weather that causes this to happen
Britain is by a pattern were unpredictable weather problems happen.
in cold weather balloons pop i think
