Environmental Change Scenarios Development P. GOMBOLUUDEV and P.BATIMA

Slide 2

Why we are considering environmental change ? Atmosphere condition and its change are one of the constraining variables for monetary improvement of the nation Last 40 years the biological system of Mongolia is obviously changed as aftereffect of mix of environmental change and human action Mongolian biological community is exceptionally helpless and delicate to the environmental change. As a result of serious mainland atmosphere The study result gives foundation comprehend of the level of potential effects of environmental change on environment and financial parts Identify the reaction measures in human life to adjust under changes in atmosphere framework

Slide 3

Observed Global Climate Change CO 2 focus is expanded 280 ppm for period 1750 to 368 ppm in 2000, 31% Global mean surface is expanded by 0.6 0 C, land zones warmed more than seas Northern Hemisphere surface temperature is expanded over the 20 th century more noteworthy than amid whatever other century in most recent 1000 years Hot days/Heat record is expanded Frequency and seriousness of dry season is expanded by 5-10%over 20 th century Northern Hemisphere Heavy precipitation occasions is expanded at mid and high northern scope Global mean see level is expanded by 20 sm since 1900 Snow spread is diminished by 10% since 1960 Growing season is extended by 1 to 4 days for every decade amid 40 years

Slide 4

Recent Trends of Global Average Surface Temperature A blend of surface air temperature over area and ocean surface temperature over the sea. Singular bars show yearly values as deviations from 1961-1990 normal.

Slide 5

Present Climate Feature in Mongolia Climate of Mongolia is cruel mainland with forcefully characterized seasons, high yearly and diurnal temperature changes, low precipitation and generally long length of daylight in a year. Normal yearly temperatures are around 8.5 o C in the Gobi and - 7.8 o C in the high sloping territories. The great least temperature is - 31.1 o C to - 52.9 o C in January and the amazing most extreme temperature is +28.5 o C to +42.2 o C in July. Yearly mean precipitation is 300-400 mm in the mountain locales, and 150-250 mm in the steppe, 100-150 mm in the steppe-desert and 50-100 mm in the Gobi-desert ranges. Around 85-90 for each penny of aggregate precipitation falls in summer Mongolia has on a normal 3,000 hours of daylight every year

Slide 6

Recent Climate Change Trends in Mongolia During the most recent 60 years Annual air temperature expanded a normal by 1.66 0 C this expansion was more noteworthy in the winter (3.61 0 C), and littler in the spring (1.4-1.5 0 C) Winter warming is more in the high mountain locales, and less in the steppe and Gobi and desert. There is no huge changes in yearly precipitation sum.

Future Climate Change Scenarios in Mongolia Method of Climate Change Study and Its Impact Study

Slide 11

Mongolia 21-st century atmosphere changes under various atmosphere models winter precipitation change power is high than summer and summer temperature change force is high than winter It is demonstrating that winter is getting hotter and frigid, and summer is getting hot and dry
