The temperature within the cave is almost constant whatever the current surface temperature is. Once well away from surface influences, i.e., not near an entrance or another close connection to the surface, where air movements can influence the temperature, caves are usually at the same temperature (or very close) as the annual average temperature for the ...

Wind chill factors verge on being junk science, especially when interpreted uncritically. However, your physical intuition does make sense, and published formulas and tables do have a property very much like the one you have in mind: as the wind speed increases, the incremental effect of adding a given amount to the wind speed gets smaller and smaller. For ...

Of course. You can (almost) always cool down a 4-season tent, but you can't very well protect a 2-season tent from a blizzard. The primary concern is weight, but if you're going to be camping near a glacier with -5°C winds, you'll want a sturdy tent, so that's going to come at a certain cost of weight. To keep a tent cooler, you can pitch it in the ...

Well... a 4 season tent is a 4 season tent... You can use it during the whole year without any problems while a 2 season tent might not be as pleasant during the winter. I receive questions like this all the time. "What sort of boot should I get?", Packs, tents... My answer is kind of consistent for most of them... You buy gear for what you are going to use ...

The key to cold weather clothing is viewing it as a system. The base layer of the system wicks moisture from the body and provides a small amount of insulation. The middle layer(s) of the system provide warmth and wind protection. The outer layer provides protection from the elements. That being said, a proven system for the temperature range you're ...

There is no such place. 40-60°F is a very narrow range. 20°F can be just from day and night variation, which leaves basically nothing for seasonal variation. Even if you meant daytime highs, I still don't think there is any place on earth that fits this description, let alone anywhere in the US. Let's flip this around and think of what would make ...

No there is no limit to the math of wind chill, though there is a maximum wind speed that has ever been observed. Here is what wind chill is. Imagine you have a hot cup of coffee. You can leave it at room temperature for a while and it will cool down to where you can drink it. Or, you can put it in the fridge and it will cool faster. Or put it in the ...

Your understanding of wind-chill is a bit confused. The reason the wind feels colder is because of convective heat transfer. When there is a difference in temperature between two objects, thermal energy transfers from the hot to the cold. In the case of a person in the air, the thermal energy flows into the air, and the faster the air is moving, the more ...

I don't think you will get consistent 40-60 daytime highs (what I assumed you meant) anywhere that isn't moderated by the ocean. However Fiasco is correct: The Olympic Penninsula around Sequim is very close. Summer temps are cool enough that tomatoes won't rippen outside of a greenhouse. Winter has frosts, but not consitently. The mountains nearby get ...

Many 4-season tents cannot be ventilated as well as tents made for summer conditions. Also, they tend to be larger. this means, you can use them, but it won´t be ideal. This differs a lot with the actual models you are comparing, some might be well suited for all conditions. Note that the temperature difference between summer and winter trips normally has ...

If the tent fly can be pitched without the inner then your winter tent becomes a summer tent by leaving the inner at home.

The whole concept of wind chill is not very meaningful. This can be obscured by all the fancy-looking formulas, which lend it an air of precision. It's little better than junk science, especially if used uncritically by people who assume that it must be meaningful because it's a mathematical formula. If you're completely covered and have an outer layer that ...
