How would you define weather?

Answer 1

Weather is a term that encompasses phenomena in the atmosphere of a planet. The term usually refers the activity of these phenomena over short periods, such as hours or days. Average atmospheric conditions over significantly longer periods of time is known as climate.

Answer 2

I'll start by saying that putting a question mark on the end of sentence does not make it a question. If you want to know the difference between climate and weather, you should ask that. Here is the definition of climate from the Glossary of Meteorology, Second edition: "The slowly varying aspects of the atmosphere–hydrosphere–land surface system. It is typically characterized in terms of suitable averages of the climate system over periods of a month or more, taking into consideration the variability in time of these averaged quantities. Climatic classifications include the spatial variation of these time-averaged variables. Beginning with the view of local climate as little more than the annual course of long-term averages of surface temperature and precipitation, the concept of climate has broadened and evolved in recent decades in response to the increased understanding of the underlying processes that determine climate and its variability." The Glossary does not define weather, but it is pretty much the instantaneous state of the atmosphere--it's what you experience when you walk outside Personally I study both. I would never consider studying climate without also having a good understanding of weather, so even though my Ph.D. may technically have come from studying "climate science," I have also spent my time studying weather (dynamic meteorology, synoptic meteorology tropical meteorology, etc.) There are certainly some meteorologists that study weather without paying much attention to climate, and there are climate scientists that don't study weather very much. To a large extent distinctions are artificial, though. However, while there are gradations between the fields, that does not mean that the techniques for studying them are the same. If I take a numerical weather prediction model, the output from the model is essentially useless past the first couple of weeks for studying weather--but that very same model may produce useful results when studying climate--because the goals are different. I hear those that deny climate science constantly claiming that meteorologists don't believe in AGW. This is complete nonsense and I think the cause is that people who I would say are NOT meteorologists, but are instead radio and television weather personalities, have expressed such views. I'm talking about people like John Coleman and Anthony Watts, who are not trained as scientists but like to claim the title because they go on the air and tell people whether they should carry an umbrella the next day. Professional meteorologists (those with degrees that do research in the field) by and large understand the cause and consequences of AGW.

Answer 3

The state of the air or atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness, or any other meteorological phenomena; meteorological condition of the atmosphere; as, warm weather; cold weather; wet weather; dry weather, etc.

The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.

Answer 4

Weather is a set of all conditions in a given atmosphere at a specific time.

Answer 5

Weather is the changing atmospheric conditions.

Answer 6

Weather is a term that encompasses phenomena in the atmosphere of a planet.

I agree with him/her

Answer 7

The condtion of the atmosphere at one given point.
