| Freak weather offshoot of climate change:Experts |
| Intermittent showers in Hyderabad have bewildered Meteorologi- cal officials, while climate change experts said it is increasingly becoming difficult to predict future weather events in the country. For the last two years, we have noticed that the weather systems are behaving in a peculiar way resulting in unusual weather events. | After observing such unforeseen situations like extreme summer in the country, sudden hailstorm in Chevella region of Ranga Reddy district, cloudbursts in Uttarakhand and early onset of southwest monsoon and a late retreat, experts say that weather systems are behaving in a peculiar way. | Ongole received 341 mm rainfall in one day, which is more than one- third of the state's total annual rainfall. The heavy showers across the state have damaged several acres of crops, particularly cotton. But in a good news, 75% of the around 80,000 tanks in Andhra Pradesh are full now.

The state of atmospheric conditions of elements like sunshine, temperature, atmospheric pressure, winds, humidity, clouds and precipitation over an area at a particular time refers to weather. These weather conditions fluctuate very often even in a short period. Climate refers to such conditions over a large area and follows a similar general pattern over 30 or more years. There will be variations from year to year but the basic pattern remains the same. On the basis of these generalised conditions, the year is divided into seasons. The pattern of the elements of weather and climate for a place can be shown using pictures called climographs or climatographs. Climographs show average monthly values of maximum temperature, minimum temperature and rainfall for a given place.
