The influence of climate upon the number of weather-working hours in combine harvesting in the Netherlands
article
An outline is given of a method of estimating the number of hours during which the combine harvester can be operated in a certain harvesting period. This method is based on a study of the relation between the daily rainfall and the hourly estimates by 60 observers of the possibility of combine harvesting (weather-working hours). Over the years 1964, 1965 and 1966, the relationship between the possibility to combine harvest and the rainfall has been summarized in a linear regression equation:y=a+b 1 x 1+b 2 x 2, withy=mean number of weather-working hours per day per half-monthly period, x1=mean daily rainfall per half-monthly period, x2=number of dry days per half-monthly period. For chosen percentiles of the frequency distribution ofy the corresponding number of weather-working hours in the same period can be estimated for future years. Taking the (two dimensional) frequency distribution of x1 and x2 as fixed, confidence intervals for the estimated number of weather-working hours can be calculated.
