In Fig.21 the summer (March-May) and winter (January-February) season mean maximum and minimum temperatures map are given. It shows mean maximum summer temperature based on 2013 to 2020 data shows maximum over north, eastern and extreme southern districts Jogulamba Gadwal, Wanaparthy and minimum over Rangareddy and mean minimum winter temperatures shows, highest over Nalgonda, Suryapet, Khammam, Hyderabad and lowest over Adilabad, Kumuram Bheem, Nirmal, Kamareddy, Rajanna Sircilla and Sangareddy. Fig.22 Box plot representing the month wise mean, maximum and minimum temperatures (°C) data are given. It shows, gradual rise of maximum and minimum temperature from February with peak in May and fall after onset of monsoon in June followed

by July-August with heavy cloudiness and slight rise in September-October due to partly cloudy and increasing solar insulation than followed by fall from November to January during the winter season. Year wise variation of annual (June-May) mean and May maximum temperature from 2013 to 2020 are given in Fig.23(a & b). It shows, during the last 7 years, the annual mean and May month maximum temperatures are shown slight increasing trend with highest mean temperature in 2015-16 and highest maximum temperature in May 2018. Telangana state experiences mild winter from November to January. The extreme minimum temperature in winter reached below 5.0°C in some years over Adilabad, Kumuram Bheem, Kamareddy, Nirmal, Nizamabad, Mancherial, Jagtial, Medak, Rangareddy and Sangareddy districts. In addition to low temperatures, strong northerly cold winds from central India also make more uncomfortable with windchill over the region. The wind chill is de ined as: simply the feels-like temperature. It is based on how much heat is lost from the exposed skin, which is caused by cold temperatures and windy conditions. Wind chill numbers are always lower than that of air temperature values. Sometimes the wind chill factor also extends to central districts of state when there is an advection of cold northerly wind to central districts. The diurnal variation of maximum temperature during summer shows the day temperature gradual rise from 11:30 a.m. to 03:30 p.m. and after 04:30 p.m., the temperature shows a sudden fall of 6° to 8°C in 2 hours from 04:30 to 06:30 p.m. (Fig.24a). The same trend was observed in case of winter minimum temperature also. During the night, it shows a gradual fall from 12:30 mid night to 05:30 a.m. morning and after 06:30 a.m., temperature shows a sudden rise of 5° to 8°C in one hour from 06:30 to 07:30 a.m. (Fig.24b). This sudden fall /rise of temperature after sun set/rise is because of semi-arid nature of soil.
