| Early
July had very little northward flow and the |
||||||
| RI
had very little amplitude as it went down below |
||||||
| zero. As a result, daily rain was low. |
||||||
| An
upward trend becomes clear on July 14 and the |
||||||
| crossover
occurs a day later. According to
the |
||||||
| crossover
rule, the next 7 to 10 days should be |
||||||
| wetter
than the last several days. This
case is one |
||||||
| of
the better examples of successful application of |
||||||
| the rule. |
