      @greatkingnan Hello, detailed forecast or Rain, Thunder layer shows different data based on different calculations. Detailed forecast is more precise if you want to check the predicted amount of precipitation.

          What is the arrow on my location pointing towards? As I turn to face a different direction, the arrow swings to point toward something else. It's not making any sense to me; what is its purpose?

            This arrow appears at your GPS position on the Radar layer and shows a fixed or inconsistent direction. It has no use.

              Hi,
              I wanted to know what criteria you use for the elaboration of the meteograms. this is the one from the ECMWF.

                    On the Meteogram, what does the letter 'K: at the cloud base mean ? I have it set to show it on feet, but soem shows for example 17K

                      @mark-mansfield I think it means thousands (of feet) altitude.I think

                        @jp_windy65535 thank you, that does make sense, but then why does some heights show as feet , for example 6900, and others as 15K for example?

                          Hi, Precipitation is indicated in mm (millimeters) as I understand the intensity of precipitation? Or accumulation? if intensity, then probably the dimension is mm/minute? And if so, then it can be daily, semi-daily. can you clarify? Привет, осадки, указаны в мм ( миллиметры) это как понимаю интенсивность осадков? Или накопление? если интенсивность, то наверное размерность мм/минуту ? И если так, то она может быть суточная, полу суточная. можно уточнить?

                            It is not the intensity of precipitation per minute. It is the rain forecast during 3 hours.

                              Hi! What does the number in the convective mean? Is it a probability of lightnings somehow? If there is 1.4 for example does it mean 1.4 mm of convective rain? Is there a way to predict the change of lightning somehow? Is 1.0 very little or a lot? Many thanks already! Windy is the best weather app :)

                                @timoti Hello, the number indicates what amount of rain is from convective origin.

                                  Hi @Korina is it possible to display the "rain" and "convective rain" as a daily sum? For example, in the Figure shown below, the accumulated rain for martes 14 (tuesday) would be 15,4 mm of rain and convective rain. In case your answer is no, do you have a Python library which could advice me by solving my rerquirement.

                                  260ce4bf-4ae0-4042-995f-b0b34300d40a-image.png

                                  Thanks!

                                      @sochagota Hello, there is no way to display those values as daily sum. The alternative is to use Rain accumulation layer.
