Weather Tidbits: Solar Seasons
Solar seasons are explored in this Weather Tidbits. Solar seasons are based on insolation (solar radiation); where the solstices and equinoxes are viewed as the midpoints of the seasons. Solar seasons change about 3-4 weeks ahead of the meteorological seasons and about 6-7 weeks ahead of the astronomical seasons (equinoxes or solstices). Spring consists of increasing insolation or solar radiation with the months of February, March and April. Summer is the months of maximum insolation which are May, June and July. Autumn involves decreasing insolation that includes August, September and October. Winter is when the insolation is at its minimum in the months of November, December and January.
