148 | ! |
---|
149 | ! this routine generates daily weather conditions from monthly-mean |
---|
150 | ! climatic parameters |
---|
151 | ! |
---|
152 | ! specifically, this routine generates daily values of |
---|
153 | ! |
---|
154 | ! - daily total precipitation |
---|
155 | ! - daily maximum temperature |
---|
156 | ! - daily minimum temperature |
---|
157 | ! - daily average cloud cover |
---|
158 | ! - daily average relative humidity |
---|
159 | ! - daily average wind speed |
---|
160 | ! |
---|
161 | ! in order to generate daily weather conditions, the model uses |
---|
162 | ! a series of 'weather generator' approaches, |
---|
163 | ! which generate random combinations of weather conditions |
---|
164 | ! based upon the climatological conditions in general, |
---|
165 | ! this weather generator is based upon the so-called Richardson |
