Drought is expected to occur 20 - 40 percent more often in most of Australia over the coming decades.6, 18 If our heat - trapping emissions continue to rise at high rates, 19 more severe droughts are projected for eastern Australia in the first half of this century.6, 17 And droughts may occur up to 40 percent more often in southeast Australia by 2070.2 Unless we act now to curb global warming emissions, most regions of the country are expected to suffer exceptionally low soil moisture at almost double the frequency that they do now.3 Studies suggest that climate change is helping to weaken the trade winds over the Pacific Ocean, with the potential to change rainfall patterns in the region, including Australia.20, 21,16,22

The Palmer Drought Severity Index, which is a measure of soil moisture using precipitation measurements and rough estimates of changes in evaporation, has shown that from 1900 to 2002, the Sahel region of Africa has been experiencing harsher drought conditions.

Six Chinese scientists used remotely - sensed imaging data, including leaf area index (LAI), normalized difference vegetation index (NDVI), an enhanced vegetation index (EVI), gross primary production (GPP) and net primary production (NPP), coupled with other data (temperature, soil moisture, evapotranspiration, albedo and wind) over the period 2003 to 2014 to analyze the effects of a wind farm on summer vegetative growth in a region of northern China.

Depending on the region, the persistence from spring to summer of soil moisture or snow anomalies generated during spring by temperature and precipitation variations may explain river flows variations in summer, when no concomitant climate variations exist.

The averages for the last 12 months show dry conditions over most regions within a large belt stretching across parts of both Europe and Asia, with below average precipitation and soil moisture and much below average relative humidity, starting in south - western Europe and ending near Japan.

The warm colours used to denote above - average temperatures are used to denote regions that are drier than average, while shades of blue denote above - average precipitation, relative humidity or soil moisture.

For southeast Europe the situation is more complex, with below average relative humidity and soil moisture in the whole region, but with some areas, such as large parts of the Alpine region and the countries adjacent to the east coast of the Adriatic Sea, having experienced above average precipitation.

This led to soil moisture returning to close to average, thus ending the run of much below average soil moisture in this region.

By autumn a large soil moisture anomaly remained in the whole region and according to the estimates from both products, further increased both in amplitude and extended further south of the Baltic Sea.

Direct observations of soil moisture are not assimilated; analyses are constrained instead by the mismatches between synoptic temperature and humidity observations and corresponding background forecasts, in snow - free regions when meteorological conditions are appropriate.

Also, should we consider the productivity of agricultural regions due to the effects of climate (i.e. precipitation, soil moisture, days of sunlight and temperature), or can technology yield independence from these external influences also?

Since the soil moisture in permafrost regions in the warm period is already very high, evaporation would not necessarily increase.

«Recent research, however, suggests that there is a possibility that this gradual global warming could lead to a relatively abrupt slowing of the ocean's thermohaline conveyor, which could lead to harsher winter weather conditions, sharply reduced soil moisture, and more intense winds in certain regions that currently provide a significant fraction of the world's food production.

As noted in the TAR (McAvaney et al., 2001), vegetation change during the mid-Holocene likely triggered changes in the hydrological cycle, explaining the wet conditions that prevailed in the Sahel region that were further enhanced by ocean feedbacks (Ganopolski et al., 1998; Braconnot et al., 1999), although soil moisture may have counteracted some of these feedbacks (Levis et al., 2004).
