The following is true of weather: PATTERN MAY CHANGE FROM HOUR TO HOUR OR FROM DAY TO DAY.
Weather refers to the atmospheric condition in a particular place over a short period of time. Weather is measured by considering different variables such as temperature, relative humidity, precipitation, etc. Climate on the other hand refers to the weather condition of a place that is measured over a long period of time, normally over a period of 30 or 35 years.
