How do weather forecasters know the Sun will generate x-amount of heat five days in advance?

Friend of mine was a meteorologist: "I have the only job where you can be wrong everyday and your boss still says 'See you tomorrow,'"

Yeah but they're not wrong everyday.

How do they know on the days they're right what the Fusion of the Sun was going to be?

How do they know? They wet a finger..the middle finger and hold it 7 feet 1 1/4 inch off the ground to tell the speed and direction. Then its as easy as 1+1=2

perhaps the sun is just a ball that only produces light, all weather effects are created by them and we are made to believe it is another way!

1+1=2

Right, but five days from today is the future!

How do weather forecasters see into the future of what the Fusion of the Sun will be five days in advance?

I believe you are partially right.

IMO the sun's light carries heat.

The energy of the sun is relatively constant.

As for differences in the ambient temperature?

With the variables as subtle as the beat of a butterflies wings to wind flowing through mountain passes to the changing exposure angles as the earth orbits, these being numbered close to infinity; yes you are going to get different weather patterns.

As for your question.

In order to know the value of x-amount, they have to calculate what they think is the amount needed to create the observable weather patterns.

That total average would not vary appreciably day to day.

Predicting WHERE any particular weather pattern will be is another thing entirely. And forecasters do on average make pretty decent 5 day forecasts.

Apparently you are assuming that because the weather changes in any particular area the Sun's output changes.

Sunspot minimum and maximum have an appreciable effect on the Sun's energy output. But the time frame of cycles is in years not days.

It is?

Then why does the sun feel and register hotter on some days more then others?


This difference in temperature is created by the Sun because the Sun doesn't heat the earth at the same constant heat.

Omitting the seasonal tilt.


I didn't ask about weather patterns.

I asked how weather forecasters know when the Fusion of the Sun will generate more heat five days in advance.


Yes, the sun created these weather changes.

Because the Sun doesn't heat the earth at the same constant heat this difference in temperature gives us the Cold Fronts, Warm Fronts, jet stream ridges, jet stream troughs, high + low pressure systems, sea surface temps giving us the winds.

Chance.

holy fuck canada!

distance between the sun and earth is not constant. they go by records and make predictions.

Thanks, I needed that!

Because it already happened

Yup

Wouldnt that be a trip.

No my friend YOU are making invalid ASSUMPTIONS.

You ASSUME the Suns energy is changing by YOUR observations of weather patterns.

Truth is YOUR question isn't valid because it makes an unfounded and UNTRUE assumption as a parameter of the question.

This isn't unique to only me.

Its not either an assumption, my skin feels the sun hotter and my thermometer does too on some days more then others.

The question necessitates a truthful answer and because science is lacking of truth is what's proving difficult, therefore making an unfounded judgment that weather forecasters do not give a long term forecast knowing when the Fusion of the Sun will generate more heat five days in advance shows your unwillingness to seek the truth of this matter and bring it forth with all honesty regardless that it grinds against the indoctrination of the scholastic systems and what they deem as accepted.

They estimate and change when closer

Uh the heat is not from the Sun only.

The heat comes from the pressures in the atmosphere, not space. High pressure involves sinking air, the sinking air heats up as it descends causing heat.

Low pressure has air rising, sucks the hot air up ... cools the land down ...

Sun has nothing to do with heat/cold on the surface.

So we know the forecast by looking at the coming high/low pressure systems.
