A variation on the [https://jussilanet.com/chartstermiset.htm Thermal Seasons] chart by [https://cumulus.hosiene.co.uk/memberlist.php?mode=viewprofile&u=16853 @Pes]. This interesting chart, together with the Temperature Sum and the Growing Degree Days it forms the set of Agricultural related charts, displays the proportional contribution of the seasons in the year where the boundaries between the seasons is simply defined by temperature. This graph will be more important in the Nordic region where the growing season is short and requires careful planning. While the plant breeders push the plants north, the farmers need to make it work. This type of charts helps. And on the other hand: the temperature limits of the seasons thermal season vary with latitude: where Finland lets the spring start at 0 °C, in the Netherlands I use 5 °C simply because otherwise there would not be a winter at all (which would not be correct because plants and animals are in rest). Anyway, this chart is also an heuristic and the limits can be defined by the user with the inifile parameters ''WinterToSpringTemperatureLimit'' and ''SpringToSummerTemperatureLimit'' which hold defaults of 0 °C and 10 °C (based on Finland).
