Discussion Overview

The discussion revolves around the timing of the summer solstice, specifically whether it is starting earlier than expected, and the implications of this on day length and heat waves. Participants explore the relationship between astronomical events and observed weather patterns, including historical temperature records.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes that sunrise and sunset times suggest the summer solstice is occurring three weeks early, questioning if the first day of summer will be longer this year.
  • Another participant emphasizes the need for more observations, stating that day length changes little around the solstice and that the earliest sunrise and latest sunset do not occur on the solstice itself.
  • Some participants mention the influence of el Niño/la Niña phases on current weather patterns, suggesting that unusual weather may be related to these cycles, though this does not affect the timing of the solstice.
  • A later reply discusses the gradual shift of the solstice timing due to the precession of the equinox, indicating it takes a significant amount of time for the solstice to occur one day earlier.
  • There is a suggestion that while heat waves are not random, the causes are not well understood, highlighting the challenges in predicting such phenomena.

Areas of Agreement / Disagreement

Participants express differing views on the implications of the observed sunrise and sunset times, with some agreeing on the need for more data while others focus on the broader context of climate patterns. The discussion remains unresolved regarding the relationship between the solstice timing and heat wave patterns.

Contextual Notes

Participants note that the relationship between astronomical events and weather patterns is complex, with various factors influencing observations. There are mentions of the need for further observations and understanding of atmospheric sciences to clarify these relationships.

Sunrise is at 5:30am and sunset is at 8:30pm and it is only May 30th. That is 3 weeks early for summer solstice. Is the first day of summer going to be longer this year? Also on the east coast it was the hottest it has been since 1885. Is there any pattern to the heat waves or is everything just random? Thank you for any answers I can get.

While Evo's link is close it simply does not answer the question.

It is good that you are observing sunrise and sunset times; however you need to make more observations. What you will find is that the day length will change very little between now and the solstice. If fact it will not start changing again until about a month after the solstice. The day length changes rapidly for about a month each side of the equinox in Sept and March. It changes very slowly for a month on each side of the solstices in June and Dec.

If you continue making observations you will discover some interesting things. You will discover that the earliest sunrise and the latest sunset do not occur on the solstice. They are offset several weeks each side. For more info Google the "equation of time".
 
Uh, I would point out that we're currently in the transition period between elNino/laNina phases of the global weather cycle, when weirdness often happens.

What's happening beyond the Arctic Circle is another, much-disputed matter entirely.

This has nothing at all to do with causing when the solstice occurs.

The solstice is getting earlier, but not by much. It will take some 71 years to occur one day earlier. This is due to what is called the "precession of the equinox".

As to your question asking if everything is random. No, it is not. However, we simply don't know enough about what causes such things as heat waves to predict them very accurately. Leaning enough to do so is one of the major purposes of the atmospheric sciences.
