The trend at the new location seems to be for higher evaporation rates, as noted in the generally higher totals after 1960. Table T. Climatic Data, Cow Creek, Calif. (Eiev., Y 25') The criteria of at least three consecutive months with average maximum temperatures of 100°F. or over was set up by Russell as the boundary between B\iVh and BWhh climates. Five of the several California climatic stations that fall into this "very hot" category and their mean monthly maximum temperatures for the warmest months can be noted in Table 2.

This is the small "m" for monsoon type precipitation (in this case, with reference to heavy seasonal precipitation). Precipitation data from various stations in northern California were plotted on a graph (Figure 2) by utilizing Koppen's formula for delimiting "m" areas. It was found that in the north coastal area two separate regions, one in Del Norte County and extreme western Siskiyou County (east of Crescent City) and the other in Humboldt County (southeast of Eureka), have this type of climate (See Figure I). 4
