writes This site sort of confirms what i thought: http://www.worldtime.com On the following page it gives sunset and sunrise times for various cities. Edinburgh, Liverpool and Cardiff have about the same sunset. Coventry and Newcastle have the same slightly earlier sunset and they're all later than London. So, it's the east-west that affects the sunset time, and its the north-south that affects how strong the sunlight is. Around the equinox (as we are now), north and south have similar length days, but the latitude comes into play the further away we are from the equinox roughly 8 mins for every 1 degree of latitude. Think about it - at the equator, the day length in our midsummer is 12 hours; at the N pole the day length is 24 hours. So either there is a line somewhere, N of which the day is 24 hours and S of which, 12 hours; or the day gradually grown longer the further north you go. -- Kay Easton Edward's earthworm page: http://www.scarboro.demon.co.uk/edward/index.htm |

I do stand by my advice -- the more sun, the better. Depends what you're growing and at what latitude. Jo is in France; further south and warmer than the UK with less cloud cover, more sun, and more intense light. In some circumstances, afternoon shade and wind shelter could be preferable. Hot afternoon sun and wind together is fine for herbs, maquis and coastal plants with narrow/ hard/ silvery leaves etc but can be a deadly combination for plants with large soft green leaves like tomatoes, lettuce, beans or potatoes. I'm going to have to draw some diagrams for myself. :-) I know that the further north you (in the northern hemisphere), the longer the summer day is. It may be true that the sunlight is less intense, however. In midsummer we get nearly 23 hours of daylight, but it's nothing like the brilliant high-intensity light nearer the Equator...cloudy skies are a common feature of north UK summers. They certainly grow veg, incl. tomatoes in Fairbanks, which is approx. 65N. There's a big difference between continental climate and the UK's maritime one. Janet. |

Right. It doesn't seem fair that NW Europe gets all the benefit of the Gulf Stream, which just waves at us as it zips north. The winter I was in Stavanger, Norway, it only got down to 0C just one night between New Year's and mid-February. Here at home there were 2 blizzards and nightime temperatures around -10C, in spite of being nearly 15 degrees further south. AND on the coast. Back to the sun question, it seems that northern sun, even in winter, *is* 'thinner'. However, all the more reason to locate a garden where it gets every bit that's available. |

"Janet Baraclough.." wrote in message ... The message from "Martin Sykes" contains these words: "Kay Easton" wrote in message ... Eh? So why in summer is sunset later in scotland compared to SW? My 'guess' (and I may be completely wrong here) is that if you look at a map, Scotland is further west than most of England but we are in the same time zone. The further west you are, the later the sun will set so I'd expect that if you look at the figures closely, the sunset time in Scotland say for Glasgow, would be similar to that for Cornwall and both would be much later than sunset in Kent. You are completely wrong :-) The far north of Scandinavia is called land of the midnight sun..the nights hardly get dark at all. In midsummer, Scotland also gets very short hours of darkness; much shorter than Cornwall. In midwinter Scandinavian people get very little daylight and Scotland is pretty dim too..a bare 7 hours. Much darker than Cornwall. Janet (Scotland) Absolutely correct.. for Scotland I mean In the height of summer it doesn't get dark and in winter I go to work in the dark and return in the dark:( Ophelia |

I'm replying from work via Google and was going to reply to Janet but
for some reason she doesn't show up in google groups !? ( I'm not completely wrong, but definitely missing a big part of the picture ) The sun does set later as you go west but because of the angle of the earth's axis, it's not quite as simple as I suggested and is affected by latitude too. That's sort of irrelevent though because as others pointed out, it's the day length and strength of light that matters, not what the time of day is. So some other questions: Is it better for plants to have long days of weak sun, or shorter days of strong sun? At which latitude is the greatest total amount of energy received from the sun each day? How does it affect plants which are regulated by day length? Is it the angle to the sun or is it the extra atmosphere that the light goes through? If it's really just the angle, then I should be able to get tropical levels of sunlight by rigging up a suitably angled mirror to reflect the light. eg. at the poles, a mirror of 1m*1.41m at 45 degrees would catch 1 sq m of light and reflect it to the ground as if it had come from directly above. Maybe this could be designed into greenhouse roofs so that they had one side of the roof angled with mirrors instead of glass to give the effect of direct sunlight from above? |
