Sentences with phrase «overall precipitation amounts»

The chemical nucleation process creates an endothermic reaction that tends to reduce the overall precipitation amounts.

Basic theory, climate model simulations and empirical evidence all confirm that warmer climates, owing to increased water vapour, lead to more intense precipitation events even when the total annual precipitation is reduced slightly, and with prospects for even stronger events when the overall precipitation amounts increase.

Not exact matches

But beyond the increased amount of precipitation, Wehner adds, «this study more generally increases our understanding of how the various processes in extreme storms can change as the overall climate warms.»

Campbell River also ranked poorly on our list for both its high number of wet days and overall amount of precipitation, although its fair temperatures meant it had few days below zero.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

In agreement with the results of their study, the contribution of variability (i.e. amount of precipitation during the driest and the wettest quarters) in our model was low; nevertheless the overall geographic fit of the model was improved when those two variables were included.

[1] However, snow water equivalent — the amount of water contained within the snowpack — has lagged overall precipitation.
