Answer:
Weather refers to short-term atmospheric fluctuations, whereas climate explains the weather in a certain place over a long period of time.
Explanation:
Globally, weather conditions are measured at hundreds of locations every day of the year by observers and automated stations. Some remarks are made every hour, others perhaps once a day. In the long run, these weather observations allow us to quantify average long-term conditions, giving an insight into the climate of the region.
Systemic weather records have been recorded for over 140 years in various places in the United States. We can recognize patterns and trends with these long-term records. And it's our mission to collect, monitor, and arrange these data, as the official repository of the Nation for environmental data, for scientists, decision-makers, and you online.
