Modern meteorologists use the numerical weather prediction method. This method uses mathematical simulations of the earth to predict the weather. A number of simulations are run in different countries worldwide, using weather observations relayed from weather satellites as inputs to the simulations.
They also need wind vanes, thermometers, ocean thermometers, ground thermometers, solar panels, rain measures to get accurate results.


Mathematical simulations can be used to generate either short-term weather forecasts or longer-term predictions. The improvements made to the simulations have allowed for many improvements in tropical cyclone tracking and air quality forecasts.
Manipulating the massive amount of data and performing the calculations necessary requires some of the most powerful supercomputers in the world. Even with the increasing power of supercomputers, the forecast of the simulations is only six days. Factors affecting the accuracy of predictions include amount and accuracy of observations, as well as problems in the simulation code.

How can you observe weather?

An affordable and simple way to is to just go outside, take measurements of precipitation, identify cloud types, and to take note of "what is in the air" such as humidity perc

Is error possible in weather predictions how and why?

Yes. First, making an accurate prediction requires getting good,  accurate data, but there are limits to how much data we can gather.  A small variation in one weather condi

How does a groundhog predict the weather?

It predicts the weather based on whether it sees its shadow or not. It's simply American folklore and whether it sees its shadow has no bearing at all on the next 6 weeks of w

How do people predict the weather forecast?

They use historical data to predict what the weather will be like in the immediate future.

What flower can predict the weather?

  Flowers to predict weather:   Scarlet Pimpernel, morning glory, pinecones

How does air pressure predict weather?

In general High Pressure promotes atmospheric stablity (clear sunny weather) and warmer temperatures, while Low Pressure promotes atmospheric instablity (storminess) and somew

How do weather stations help predict weather?

To answer this you need to understand what atmospheric pressure a.k.a. barometric pressure is. This is very simply the weight of the air mass that is sitting on top of your lo

How do weather maps help weather forecasters predict weather?

Weather maps help predict weather because weather systems are under  the influence of prevailing winds and jet streams. For example "Nor  easters" come from the south west a
