what is climate?what are its advantages?

Answer 1

The climate (from ancient Greek: κλίμα, "clime") is commonly considered to be the weather averaged over a long period of time, typically 30 years. Somewhat more precisely, the concept of "climate" also includes the statistics of the weather — such as the degree of day-to-day or year-to-year variation expected. The Intergovernmental Panel on Climate Change (IPCC) glossary definition is:

Climate in a narrow sense is usually defined as the “average weather”, or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years. The classical period is 30 years, as defined by the World Meteorological Organization (WMO). These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system.

Answer 2

Climate is the weather pattern in a given geographical region over a long period of time. Climate in itself has no advantage or disadvantage, you could describe a warm or cold climate, rainy or dry climate, all of which would have various advantages or disadvantages. For example if you're in a warm, dry climate such as the desert it is a disadvantage for growing most crops but it is probably an advantage for people suffering from certain allergies as the plant allergens are not present in the numbers that they would be in a wetter climate.
