Over the past 70 years, Mongolian land surface temperature rose by 2.24C degrees and the amount of precipitation reduced gradually.
Summer temperature has risen by 2.4C to 4.2C degrees and the amount of precipitation reduced by 8-10 percent. Central regions of the country have seen the rapid change in temperature and amount of precipitation.
LESS PRECIPITATION IN INNER ALTAI
In the first quarter of Apr 2017, 1-12 mm rainfall occurred in most regions and air temperature was warmer than climate average.
Precipitation and snow are expected in Central and Gobi regions on Apr 19, Northern parts of Eastern regions on Apr 20, some parts of Central and Eastern regions on Apr 22, 26 and Eastern parts of East regions on Apr 23-24 and Apr 27. On these days, winds will reach 12-14 m/s in Gobi and steppes as well as dust and snow storms will occur.
Day temperature will be 3C to 8C, night temperature will be -6C to -11C in Eastern regions on Apr 22-24. Day temperature in Gobi regions will be 11C to 16C and it will be -3C to -8C at night. Warm days are expected remaining days while day temperature will reach 17C to 22C in Gobi regions.
NATURAL DISASTER PREDICTED
In May 2017, an average air temperature will be 5C to 10C in mountainous areas, 15C to 19C on Gobi regions and 9C to 15C in other regions. 5-10mm precipitation will occur in Western and Gobi regions and 12-30 mm precipitation is expected in other regions.
Meanwhile, huge amounts of precipitation are expected in most parts of Bayan-Ulgii, Uvs, Arkhangai, Bulgan, Selenge provinces, Northern parts of Hovd, Bayanhongor, Tuv, Hentii provinces, Eastern parts of Zavhan, Huvsgul, Umnugobi provinces, Southern parts of Dundgobi, Dornogobi, Sukhbaatar, Dornod provinces. Only Inner Altai will receive less precipitation than average in May.
In recent years, rising air temperature and reducing precipitation have caused droughts and decreasing soil moisture in farming fields.
In 2017, natural disasters including extreme heat, temporary heavy rains, hail, and flood are likely to hit the country as well.
Moreover, sudden cold and snow expected at the end of May will negatively impact on crop growth.
