Doesn't Target: Wastelands say it's a desert? I think it does mention that, but not sure.
Toturi, you're acclimatised to the humidity and heat levels. However, a runner from the Sprawl is going to suffer from heat and humidity just as much as I would, quite possibly more cos isn't Seattle further north than London?? And since 99% of shadowruns won't allow time for acclimatiation it's probably gonna be harsh. But okay, I'll admit I didn't see your location - I assumed you were spouting. Apologies. |

What is the average humidity in Seattle anyways?

T:WL mentions that Antarctica is dry cold as opposed to Artic wet cold.
But it is in a different section from the "normal" hot deserts. |

It doesn't matter much what the relative humidity is when you're talking about temperatures far below the freezing point of water. At 100% relative humidity in -20 degrees C the absolute humidity is 1/10th that of room temperature in 50% relative humidity, or about 1/50th that of 100% relative humidity in +38 degrees C.
The average relative humidity in an arctic climate is said to be 50-60% here. Comparing that to the relative humidity figures here makes me wonder why antarctic areas would be any dryer than arctic areas in the 2060s. So your sweat will evaporate just fine in both, assuming it doesn't freeze. This post has been edited by Austere Emancipator: Oct 27 2004, 01:21 PM |

Its all about being aclimated. I spent 8 years in Tucson playing paintball year round. I wore Full camo over lightweight clothes (T-shirt & shorts), plus a hood and full mask. Its 105F and as long as you have water, you're fine. My friends came over from San Diego CA to play and nearly dropped dead. You live in central Brazil, Thailand or any other country with constant high humidity and lush jungles you could get away with heavy armor in the jungle. Seattle to Amazonia, the runners are probably in trouble.

I think I passed out after switching to the medical removal pictures. |

Meh. I prefer some lenient interpretations of the fluff. Refrigeration systems for clothing are lightweight now, and should be able to fit within the listed mass of body armors: The coolant (water or air) circulation system is of negligible weight, 1kg today for a liquid-filled vest. The portable refrigeration system that could supply chilled coolant to that vest dropped from 21lbs to 4lbs in just a few years. The goal is to have the battery and refrigeration system down to 6lbs by 2015. The Thermal Damping option is not a particularly good approach to modeling air conditioned clothing. It stores heat and tries to prevent the heat's release, which is about as useful as ice packs for keeping cool. Effective cooling would involve a heat pump and a long-life power supply, which (as demonstrated by the batteries required for SR's laser weapons) is available in the 2050s. |

I lived in an area where Temp ar between 32 and 42 C humidity 75% to 80%.
I now live in an area where Temp is between 28 and 37 C humidity 20 to 45% I will tell you some thing, that is different. High Humidity you sweat and it stays, you get so wet with sweat that the salt in your sweat cause major chaffing on back packs. This make it uncomfortable. You will dehydrate just as quick, but are warned by sweat saturation. Low Humitity you have a dry nose your lips dry out your sweet evapourates, cooling your body. Your body is hot but not generating enough sweat so you dehydrate quicker, with out knowing. Both are bad. Factor body salts and electrolites. In both conditions body armour is uncomfortable. |

Cool. So it would be viable for them to get armor that's heat adapted. That would be great and all, if they had thought to get any new gear specifically for this run. Instead they are cutting costs by using what they've already got.
Oh, I know. My problem was that, even though I had told them that it didn't make much sense to want to wear heavy armor in the jungle. None of them thought there would be any game effects (we couldn't find anything in our books) so they were all going to wear their FFBA and long coats/great coats/secure jacket |

"You get what you pay for." :) Well, I figured my idea was an odd one and not widely adopted, which is why I presented it here to spread it. And, funny thing, I may end up using those refrigeration units I linked earlier for a RL engineering project. There's a packet of military electronics that need cooling, and they have no trouble with supplying 50 watts (or 500) for a refrigeration unit, but they are a bit hassled for spare kilograms. |

just have each of the soldiers drop a clip from their loadout, cray. at a pound and a half each, that's sure to lighten their load!

...for Shadowrun or my RL task? In RL, I'm working on a big, stationary crate of electronics, not an item carried by soldiers (except during loading/unloading from transports). |
