What are properties of weather?

Answer 1

well... there are MANY different types of data used just to predict weather... so.. wind speed, temperature, humidity %,etc. are all used into one equation to predict weather... like..... if the pressure in the area ahead of the hurricane is extremely low.. and there is a front of high pressure coming in also then you can predict that the hurricane will strengthen and its path will be changed or it will be weakened by the high pressure system... that's just an example...

Answer 2

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.

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 location. The pressure that this air exerts on you is generally measured in inches of Mercury here in the US, other parts of the world may use millimeters of mercury, Torr, kilo Pascals, or millibars depending on where you live. The units used really don't matter from a weather forecasting standpoint, all that is really necessary is to know that small variations in the barometric pressure can result in big changes in the weather.

Low pressure generally brings rain. In areas of low air pressure, the air is less dense and relatively warm, which causes it to rise. The expanding and rising air naturally cools, and the water vapor in the air condenses forming clouds and the drops that fall as rain. Conversely, in High pressure areas the air is more dense and relatively cool, which causes it to sink. The water vapor in the sinking air does not condense, leaving the skies sunny and clear.

A good quality weather station incorporates a pressure sensor and outdoor temperature and humidity sensors. Using the information supplied by these instruments the weather station can make fairly accurate predictions of approaching weather. The weather stations that Chaney Instruments manufactures incorporate a special learning mode so that they will automatically compensate for the altitude in your location.

Answer 4

When you look at your weather instruments and the radar. You and the meteorologists can get a general idea of what the weather is going to be like. Then again, they can be wrong, forcasts do change though.

Answer 5

Weather properties are such as things like humidity and air pressure.
