|---|
| 134 | !! climatic parameters. |
|---|
| 135 | !! |
|---|
| 136 | !! DESCRIPTION : Specifically, this routine generates daily values of |
|---|
| 137 | !! - daily total precipitation \n |
|---|
| 138 | !! - daily maximum temperature \n |
|---|
| 139 | !! - daily minimum temperature \n |
|---|
| 140 | !! - daily average cloud cover \n |
|---|
| 141 | !! - daily average relative humidity \n |
|---|
| 142 | !! - daily average wind speed \n |
|---|
| 143 | !! In order to generate daily weather conditions, the model uses |
|---|
| 144 | !! a series of 'weather generator' approaches, |
|---|
| 145 | !! which generate random combinations of weather conditions |
|---|
| 146 | !! based upon the climatological conditions in general. \n |
|---|
| 147 | !! This weather generator is based upon the so-called Richardson |
|---|
| 148 | !! weather generator. \n |
