Climate v/s Weather v/s Climate Change...10th December

Every season a powerful storm impacts our region, there tends to be  a common types of responses. If a storm brings heavy rains and damaging gale winds, some claim it is " climate change".

In the event a heat wave or other warm-weather type of event impacts the area, others claim climate change is verified.
In truth, neither of those outcomes are true, because weather events do not directly connect to climate.
So, what is weather, and how is it different than climate?
Weather
To put it in one sentence, weather is what all of us experience on a daily basis.
Weather describes the atmosphere at a specific place and time, including temperature, pressure, humidity, sunshine, rain, or cloud cover, winds, hail, snow,  flooding, blizzards, thunderstorms, heat waves, hurricanes etc.
Meteorologists use various tools to take real-time observations of these variables on a minute-to-minute basis.
One way to think of things is that weather is what you get, whereas climate is what you expect.
Climate
While weather describes the atmosphere down to the minute, climate describes the average conditions expected at a specific place at a given time.
Climate is most frequently used on a 30-year scale, averaging together weather information such as pressure, temperatures and precipitation.
This is how the average high and low temperatures are computed for each day of the year.
Weather reports and readings mention the "average temperature" for a day, or mention that the forecast for the day is either warmer or colder than average.
Climate data can help us find out which parts of the country are typically hot and humid or warm and snowy at a particular time of year. By reviewing climate averages at a specific place, we can compare current or recent weather information to the past to help us describe whether our summer was hotter or colder than normal, for example.
Conclusion
It is incorrect to say that ONE particular storm/Event is a direct result of climate change, in one way or another, because they're different.
Climate does not cause a heat wave to impact the country, or a "Cloud burst" due to "Vortex" to impact a particular place, for example. However, over time, climate normals do change.
If the temperature were to consistently climb above 35-40c on a regular basis in June, July, and August, more often than they do now in a particular region, then this would cause 30 year "average high temperature" to rise in response.
So, while climate and weather are quite different in their execution, they are directly related.

Thanks for this clear explanation, Rajesh.

Rajesh sir so wonderful. How many of us used this terms climate and weather as being same ?? Henceforth no one would do this. Difference between climate and weather points are so clear.

Something like this was going through my mind as I read that this November was one of the warmest since 2000... How have we made it so long? All things move in cycles, especially the weather.
