Precipitation Anticipation. Bracing Up The 2021/22 Season .

Rainfall Pentads:?A rainy pentad is defined as having?25 mm or more rain in consecutive five days. It marks the beginning of the season in question and by this time, critical agronomic practices such as soil sampling should have long been done in winter to allow rejuvenation measures to take shape. Soil rejuvenation measures specifically pH adjustment, require time to act especially dolomitic lime unless one uses Maglime (liquid) and others alike that are fast acting. A weed free field throughout winter is, at this point, more quicker to achieve field moisture capacity hence early season planting is made possible to salvage the much needed heat units especially for long season hybrids that generally yield more comparatively.

How Do You Analyze Rainfall Data?

For statistical analysis rainfall data from a single series should?ideally possess property of homogeneity. This means properties or characteristics of different portion of the data series do not vary significantly. Rainfall data for multiple series at neighboring stations should ideally possess spatial homogeneity.

Analysis of rainfall data is important as it?facilitates policy decisions regarding the cropping pattern and sowing date. Observations of daily rainfall are nominally made at 9 am local clock time and record the total precipitation for the preceding 24 hours.

What Are The Parameters Used For Analyzing Rainfall?

A rainfall event is usually characterized by three parameters:?rainfall event (E), intensity (I), and duration (D). An event rainfall is the total accumulated amount of rainfall during a period of continuous precipitation, dubbed the duration of rainfall.

Rainfall intensity is defined as the?ratio of the total amount of rain (rainfall depth) falling during a given period?to the duration of the period It is expressed in depth units per unit time, usually as mm per hour (mm/h).
