The northern "spruce-line" (natural range) in Norway is not determined by climate. Spruce will happily grow much further north than that line.

Ah, I missed that for some reason. So you're saying that pine grows further NORTH than spruce in Norway!  Are you guys a bunch of insane racist pedophiles or something? That's how sick that sounds to us in North America. It's just wrong. Pine stops like 1000km south of the Spruce line. If you have some freaky pine that grows that far north, perhaps it makes sense to use a tree that has the same climatic requirements as the "tree line" marker. The spruce line is below the pine line in Finland at least. |

The northern "spruce-line" (natural range) in Norway is not determined by climate. Spruce will happily grow much further north than that line. Is it determined by soil type? Nope. It is due to barriers. Mountain ranges. Traditional theory says spruce spread slowly and was one of the latest arrivers among tree species after the ice age, coming from the east. Never made it across the mountains, as the Saltfjell are very steep even out to the coast, with numerous small fjords scraped bare by glaciers, so bad growing conditions for those trying to go around on the outside. The other mountain range is Kjølen, the one following the Norway-Sweden border. Other tree species came much earlier (except European beech), and could take advantage of the Holocen Climate Optimum 9000-5000 years ago to climb over the mountains to reach the lowland areas in the far north of Norway - or might have been spread by birds. Early invaders included birch and pine among others. Tens of thousands (millions?) spruce trees are growing north of the natural occurence now due to planting for forestry. www.skogoglandskap.no/nyheter/2012/mye_lauv_i_troms/bilde/ingress |

Wrexham seems to range between 5-10; Lerwick ranges 15-20. And I thought you said that lowland Wales held a better snowpack than Shetland...    |

Unfortuntely the map doesn't distinguish between sleet and snow. Lerwick can hold a magnificent sleet pack Surprised NI seems about as snowy as southern England  |

surprised March colder than February is rarer in the Northeast than elsewhere given how much cold Marches we've had

NSW Climate Zones My region (Oberon) falls chiefly beneath Zone 8 —"Alpine"; perhaps sourced from the Bureau of Meteorology. Climate zone 1 - High humidity summer, warm winter Climate zone 2 - Warm humid summer, mild winter Climate zone 3 - Hot dry summer, warm winter Climate zone 4 - Hot dry summer, cool winter Climate zone 5 - Warm temperate Climate zone 6 - Mild temperate Climate zone 7 - Cool temperate Climate zone 8 - Alpine The most widespread zone is Zone 4— "Hot dry summer, cool winter"; this is under a blonde/milk-like colour. Tableland regions: White = Zone 8 (Alpine); Dark Blue = Zone 7 (Cool Temperate). The white area about Sydney is not a climate zone, but instead a separate sector that you can see here, called Sydney Surrounds: www.abcb.gov.au/Resources/Tools-Calculators/Climate-Zone-Map-NSW-and-ACT ~Click "download PDF" at the bottom to get more details like I did. Fun Fact: The Alpine zone extends northwards of Walcha, Guyra and Glen Innes regions (29°-31° S)! The backcountry of the aforementioned regions (i.e. not the towns themselves, save for Guyra) straddle elevations from 1,300 upwards to 1,600 m AMSL, upon a vast scale of grazing farmland; higher than any other grazing tableland region in Australia. Mt. Kaputar (Nandewar Range; 1,512 m AMSL, 30° S), near Narrabri, lies also within the Alpine zone; very far west, too—right in the Outback! Northerly Alpine ranges include Barrington Tops, Coolah Tops, Northern Tablelands, Nandewar Range (i.e. Mt. Kaputar), and Tenterfield's very own Mt. Mackenzie.

Nevada has 12 climate zones? Some of them are tiny spots in the mountains. I count 6 that have significant area, Dsb Csb Csa Bsk Bwk Bwh |

Hardiness zones of US and most of Canada (missing a lot of Nunavut, and some NW and Yukon Territories)  |

Now a closer look at Florida, pretty decent range going from 8a (far northern Panhandle) to 11b (Florida Keys)  And one for Alaska, ranges from 1a to 8b, so the mildest parts of Alaska have roughly the same hardiness zone as the coldest parts of FL!  |

Not a scientific map, but here are the climates in Southeastern Australian that I would rate an A. Everything inside the blue line. I like to call this region "The Blue Dick"  |

An approximate map of A/B/C/D/F climates according to my preferences. Note that areas with complex topography may not be represented well.  |

Here’s some very rough boundaries of A and E/F climates in the US. Within the black circles are A climates—again rough so some may be left out or wrongfully included. The red circles represent E climates, and in the case of the PNW, some F climates as well. Looks good now!  |
