	<description>I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.</description>

		<description>What a lot of nonsense. Seasons, as far as most humans are concerned, are *climatic*, NOT *astronomical*. 

As such, specifying the solstices and equinoxes at &quot;mid-points&quot; for the seasons is utterly absurd. As someone who has studied astronomy, meteorology and climatology, I can say with confidence that my viewpoint is not as myopic as one such as Phil&#039;s who defines just about everything in life in terms of his narrowed-down astronomical worldview. No room for interdisciplinary thinking for Phil!

I have analysed mean monthly temperatures for many cities in both the Northern and Southern Hemispheres, and it turns out that the meteorological convention of defining summer as June-August, autumn as September-November, winter as December-February and spring as March-May (and the reverse for the SH) makes *far more sense* than Phil&#039;s method OR the method of defining seasonal beginnings in terms of the solstices and equinoxes. In most localities where seasons are usually well-defined (i.e. the temperate regions), defining mid September as &quot;summer&quot; and yet defining mid June as &quot;spring&quot; (which occurs if using solstices as seasonal beginnings) is ridiculous in most temperate locations,  since mid June is nearly always warmer, on average, than mid September. And using Phil Plait&#039;s method, this discrepancy gets even *worse*.</description>

		<description>HERE IN RIO DE JANEIRO, WE HAVE SUMMER AND WINTER ONLY [SPRING MIGHT BE A BETTER WORD] ALTHOUGH 40 DEGREE TYEMPERATURES IN WINTER ARE NOT AT ALL RARE. IN HTE TROPICS, THE TRADITIONAL SEASONS DO NOT MEAN MUYCH,AND THERE ARE REGIONS IN [NORTH] BRAZIL WHICH TRADITIONALLY CALL THE WET SEASON WINTER AND THE DRY, SUMMER, ALTHOUHG THE WET SEASON IS THE ATRONOMICAL SUMMER...
THE REASONS FOR THE SESONS ARE ASTRONOMICAL THOUGH,  SO IT IS PERFECTLY VALID TO USE AN ASTRONOMICAL DEFINITION. ANYWAY, IT´S IMPOSSIBLE TO DEAL WITH TWO PARTS OF THE SAME COUNTRY WHICH ARE EITHER SIDE OF THE EQUATOR WITH EXACTLY THE SAME CLIMATE....</description>

		<description>[...] Phil Plait, the Bad Astronomer pointed out when the Autumnal Equinox comes around, people call it the beginning of autumn, but he considers it to be in the middle of the season. The borders between seasons are fuzzy and vague, so for people who like fine lines in their lives, the point at which the day and night are equal in length (or technically, where the equator crosses the ecliptic) is a simple way to demarcate a seasonal transition.

		<description>I&#039;m stunned to see so many Americans using &quot;autumn&quot; instead of &quot;fall&quot;! I had no idea the term was used in the U.S.A.</description>

		<description>Meteorologists use a simple definition for the seasons because the idea that seasons, both globally and locally, have fixed starting points down to the day in the year is unrealistic. Two or three weeks, sure, but not a day. It is pretty silly to be so specific about it. So meteorological seasons &lt;i&gt;proper&lt;/i&gt; are used more for statistical &quot;binning&quot; of data than they are for explaining physical atmospheric and associated processes.</description>

		<description>I&#039;m in Birmingham, England. Today&#039;s temperature was in the mid 70&#039;s and the leaves haven&#039;t even started falling off the trees yet. Very unusual.</description>

		<description>Here&#039;s something that&#039;s pestered me for a while: If Summer Solstice is when the Sun is at its highest in the sky, and Winter its lowest, then it would follow that the Equinoxes (Equini?) are midpoints. Does the Sun rise due east and set due west on those days? (That is, at the 90 and 270 degree points on the circle, instead of slightly more north or south.) If not, when might that happen?</description>
