Then, frost or “Mae Kha Ning” is occurred.
“Mae Kha Ning” can be found in valley or great heights with temperatures around zero degrees Celsius or slightly negative. Ice Crystals often be seen cling together with grass. As the temperature turn down even more, “Mae Kha Ning” would appear in white throughout the area, including on branches and flowers. At the chilly night time, dew on the grass and leaves becomes frost or “Mae Kha Ning” when the cold air near zero degrees.
The tourist attractions where “Mae Kha Ning” can be found every year is Doi Inthanon, the highest mountain in Thailand.
