Sentences with phrase «annual precipitation decreased»

For example, [Kruss 1983] has this to say about the Lewis glacier on Mt. Kenya: «A decrease in the annual precipitation on the order of 150 mm in the last quarter of the 19th century, followed by a secular air temperature rise of a few tenths of a degree centigrade during the first half of the 20th century, together with associated albedo and cloudiness variation, constitute the most likely cause of the Lewis Glacier wastage during the last 100 years.»

A 1 degree average annual increase in summer temperatures, or a 25 % decrease in precipitation?

Predictions of the annual cycle of precipitation suggest an increase in precipitation later in the crop year (April - June) of ~ 10 % but a substantial decrease (up to 75 % at the tail) in precipitation later in the dry season (July - September).

It has been noted that an increase (or decrease) in heavy precipitation events may not necessarily translate into annual peak (or low) river levels.

The number of stations reflecting a locally significant increase in the proportion of total annual precipitation occurring in the upper five percentiles of daily precipitation totals outweighs the number of stations with significantly decreasing trends by more than 3 to 1 (Figure 2.36 c).

It is perfectly conceivable, for example, to have annual precipitation increase 10 to 20 % at the same time that mean annual surface water runoff decreases by 10 to 20 % (or even more).

Several studies focused on the Colorado River basin showed that annual runoff reductions in a warmer western U.S. climate occur through a combination of evapotranspiration increases and precipitation decreases, with the overall reduction in river flow exacerbated by human demands on the water supply.

«Indeed it is estimated that annual mean temperature has increased by over 2 °C during the last 70 years and precipitation has decreased in most regions, except the western part of the country, indicating that Mongolia is among the most vulnerable nations in the world to global warming.»
