@uhoh和你旅行的方向。If you're cycling with the wind then you get less wet, so yeah, add a wind vane to your weather station, but you still only need a cylinder for the rain gauge.

@uhoh又过于复杂;)雨仍然土地无处不在,无论风是从哪边吹过来的。一个开放的汽缸是你所需要的。

@uhoh I think you'll discover that when it's raining "big ol' fat rain" that the accumulation rate is also considerably higher than when it's a "little bitty stingin' rain" ;)

@uhoh That's overcomplicating things and you're still measuring a secondary signal that isn't what you're actually looking for (ie: the rate of water falling in mm/h or whatever). A simple rain gauge with a sensor to measure the depth of water would let you calculate the accumulation rate. Measuring weight also works, but depth is usually cheaper and easier to measure. The only thing you'd need to add is an automated dump valve when it got full. This would let you continually measure the rainfall rate and would let you record accumulation as well.

你说<代码> DateTime > < /代码,这使得我们认为。net——如果是这样,这是一个完整的,但考虑使用图书馆像< a href = " https://nodatime.org/ " rel = " nofollow noreferrer " > NodaTime < / >或< a href = " https://www.joda.org/joda-time/ " rel = " nofollow noreferrer " > JodaTime < / >(如果Java)。It's almost certain to have thought of and covered far more corner-cases than your home-rolled solution will have. If you really care about accurate time management across many time zones and many countries, you really can't beat a library (unless this component development is purely an academic exercise you're taking on for its own merits).

@DavidHammen Not really, it's still an uncertainty propagation - the complexity of the model doesn't change the mathematical techniques that are used. Certainly some models are more difficult to produce analytical uncertainties for, and much of the debate on that topic it's still really about how good our understanding is of the proxies, what their exact roles are/were, and what interdependencies may exist betwen those proxies - because all of those things affect how you formulate the model and the uncertainties generated from each input. At the end of the day, it's still all error analysis.

@Universal_learner好,这是非常重要的信息,应该在这个问题。Mediterranian盆地是一个非常不同的供水系统海洋一般。因为它太弱耦合通过直布罗陀海峡的大海这抑制了影响像潮汐,等。见:< a href = " https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2006JC004049 " rel = " nofollow noreferrer " >海平面季节周期的变化在南欧< / >同时,由于收缩海峡季节性信号相移至多个月可以显著(即:春季/秋季极值和冬季/夏季)。

@Universal_learner It's not really a frame challenge - your question simply contained a false presupposition.

你有什么证据,海平面< b > < / b >不显示季节性?什么信息让你认为海平面不会改变季节吗?清理误解可以更加容易、更加有效,通常情况下,通过了解是什么导致了误解。
