what does the high and low mean in wheather?

Answer 1

It could be one of two things. If the weather forecaster is talking about 'today's high' or 'lows of...' then it will be in respect of the temperature. High temperatures are usually given as the highest daytime temperature and the lows are usually given as the lowest night-time temperature.

There are also areas of low and high pressure. Our atmosphere is complicated and the movement of air masses caused by different temperatures moves air around, these movements result in low pressure (less air) and high pressure (more air). Generally if air pressure is increasing there will be fine, settled weather but if air pressure is falling it's probable that rain is on it's way.

Wheather Means

Answer 3

I presume you are asking about high and low pressures.Low means low pressure area(the atmosphric air colomn extending upto the top of the atmosphere over that area will have less weight) and High means high pressure area over which the above mentioned air column will have comparativly more weight.
These are caused due the differential heating by the solar radiation within land areas or between land and sea areas.Moisture in the air also contributes to the formation these low and high, particularly low pressure areas.
Moisture is present in the atmosphere in the form of water vapour which is a gas lighter than air.So a mixture of water vapour and air becomes lighter than pure dry air and the area over which this mixture lies has less weight and becomes a low pressure area.As winds move from high pressure areas to low pressure areas,they will converge here and will be forced to rise along with warm ,humid air forming clouds.So weather activity will be seen over the low pressure areas.These lows sometimes become hurricanes if favourouble condition exist.
On the other hand,dry air descends over high pressure areas where weather phenomena is very rare.
The lows and highs are the driving force of winds.

Answer 4

It is refferring to the barometric pressure. That is the atmosperic pressure. If the pressure is low (below 101 KPA) then it is likely that there will be poor weather (ex, rain, snow). If the pressure is high (above 101 KPA) then it is likely there will be good weather.

Answer 5

High is the highest the temperature will go that day. Usually this is around 3 pm. Low is the lowest it will go, this is usually sometime before dawn.

Answer 6

high pressure usually means fine weather,
low pressure changeable weather

Answer 7

It could be the temprature or barometric pressure.
