Desert-Like Conditions

By Cegeon J. Chan
STAFF METEOROLOGIST

Waking up with a dry throat? Or perhaps you have chapped lips? These problems could be blamed on the desert-like conditions entrenched in New England. Although one would generally not compare Boston to the Sahara, since last Friday, Boston has averaged a dew point of roughly 5 F . The dew point is the temperature which must be cooled to reach saturation. An increasing dew point would imply an increase in the amount of moisture. In the Mojave Desert, the average dew point over the same time period has been roughly 25 F, and hence, their air is actually more moist. Outdoor temperatures there are obviously much higher, and hence, their outdoor relative humidity is much lower. But since most of us are trapped in dorms and offices for most of the day, the relative humidity over the last 10 days is actually lower here (indoors) than in the Mojave desert!

The dry air mass can also be (partially) blamed for the lack of snow accumulations on campus from yesterday’s storm. Since it was so dry at the surface, much (if not most) of the snow evaporated before it even reached the ground. As the storm exits, windy conditions will prevail for today, lasting until tomorrow. With mostly sunny skies and calmer winds, Sunday will likely be the best day out of the weekend for outdoor activities such as skiing or snowboarding. Next week will see generally tranquil conditions. In the meantime, keep applying the lip balm.
