Weather-generating models are widely used for studying the climate change over longer periods. LARS-WG
model was evaluated for southern Telangana region
(Hayathnagar, Yacharam and Rajendranagar). A 30-
year base weather data (1980–2010) was used to generate the long-term weather series from 2011 to 2060.
The results of t and F tests at probability of 5% for
comparing means and standard deviations of monthly
rainfall and air temperatures indicated that the
observed and predicted series for the base period are
within acceptable limits. The statistics of model efficiency indicates that mean monthly rainfall and daily
air temperature are close to the predicted series over
the base period. The model efficiency was highest in
the case of Rajendranagar (98.75%). The root mean
square error and sum of square error varied from
0.4 to 1.3 mm and 615 to 1745 mm respectively. The
model predicted the maximum increase in average
annual rainfall of 5.16% in 2030 and 9.5% in 2060 for
Yacharam compared to Hayathnagar and Rajendranagar over the normal annual rainfall of the base period
(1980–2010). However, the model predicted increase
in average seasonal rainfall for Hayathnagar (6.2% in
2030 and 8.8% in 2060). In case of air temperature,
the model predicted increase in maximum temperature
in the range 1–1.53% and 2.5% for 2030 and 2060 respectively, for these locations whereas minimum temperature decreased in the range 3.7–10.2% and 6.3–
11.7% respectively, for 2030 and 2060. The performance of LARS-WG model was ranked high with
maximum model efficiency in all selected mandals of
Ranga Reddy district in southern Telangana. This
model can be replicated in other mandals of southern
Telangana as climate characteristics of the present
mandals are similar to other districts in the region
