Don’t Put Away That Jacket Just Yet
For the rest of the work week, Boston will continue to see slightly below average temperatures, with no dramatic warming trends on the horizon. The reason for these slightly chilly conditions can be blamed on the wind direction. There are three main factors in determining the temperature. The first is the sun. Obviously, it is warmer during the day rather than at night and during summer rather than winter, based on the sun’s presence. The second factor in determining temperature is cloudiness. Clouds can act to block sunlight from hitting the ground, or act like a blanket to trap heat. The third factor is the wind direction. Wind can blow warmer or cooler air into our region. Meteorologists call this phenomenon “advection.”
