After the umpire replied that it would require the oppressive conditions to lessen, a frustrated Thompson replied: Thats not going to be for hours!Its too hot, Wolf said. Sci., 67, 37393756. https://doi.org/10.1038/s41561-020-00661-5, 2021.a, b, c, d, e, f, Bollasina, M., Bertolani, L., and Tartari, G.: Meteorological observations at So now you can see all the weather data of a city has been accessed. The 400hPa wind speed above the valleys was around 3040ms1 during the 1820December period (Fig.4a, b, c), but it was weaker (2030ms1) on 21December (Fig.4d). If you dont pass country code thensearch works for USA as a default. Only really measured or calculated data is displayed in API response. Here, we write the horizontal wind in Cartesian coordinates, V=xu+yv, where u and v refer to the zonal and meridional wind components respectively. In summary, the two westernmost valleys (Gaurishankar and Khumbu; Fig.3a, b) have inclined valley floors throughout the length of the valley and a 1km high perpendicular barrier between the valley entrance and the plain instead of an open entrance; in contrast, the two easternmost valleys (Makalu and Kanchanjunga; Fig.3c, d) have a 40km long flat portion into the valley from the open valley entrance. For more details about pretty print JSON data check this. Am. I am trying to extract country weather data from the openweather api and add it to a data frame to be able to create a csv file, but I am running into some problems. 172, 133148, Stull, R.: An Introduction to Boundary Layer Meteorology, Atmospheric and Bianchi etal. The large-scale north-westerly winds at upper levels channel into the valleys, especially in the northernmost and thus highest parts of the Gaurishankar and Makalu valleys, on 18December and are seen as strong down-valley near-surface winds during the day (Fig.5a) and during the night between 17 and 18December (Fig.S2a and c in the Supplement). Subsidence warming is the dominant mechanisms leading to the heating of the air in the core of the valley in the morning transition phase, whereas the turbulent convective heat flux from the valley floor and the slopes is the dominant mechanism in the afternoon (Serafin and Zardi,2010). Bonasoni, P., Laj, P., Marinoni, A., Sprenger, M., Angelini, F., Arduini, J., You can use the following class's to insert the corresponding weather string formats. For each point on the globe, OpenWeather provides historical, current and . As we focus on the along-valley winds, it is sensible to extend the valley centre lines towards the plain over this barrier instead of following the topography towards the south-east (Fig.2b). Mikkola, J., Sinclair, V. A., Bister, M., and Bianchi, F.: Daytime along-valley winds in the Himalayas as simulated by the Weather Research and Forecasting (WRF) model, Atmos. Figure11Diurnal variations in potential temperature in the valleys at model levels 0 (ad), 4 (eh) and 8 (il) during the last 2d of the simulation (2021December2014). Calculations with the AER radiative transfer models, J. Geophys. This is quite easy, so lets do it practically in python. Add Integration button. The local wind patterns in Khumbu Valley (one of the valleys that is investigated in this study) have been studied in the past by means of meteorological observations (Inoue,1976; Ueno and Kayastha,2001; Bollasina etal.,2002; Ueno etal.,2008; Bonasoni etal.,2010; Shea etal.,2015; Yang etal.,2018) and high-resolution meteorological modelling (Karki etal.,2017; Potter etal.,2018, 2021). Bonaf, U., Calzolari, F., Colombo, T., Decesari, S., DiBiagio, C., The plain-to-valley winds basically stop between the leeward side of the barrier and the valley entrance (around grid point 110). Meteorol. Thompson, G., Field, P.R., Rasmussen, R.M., and Hall, W.D.: Explicit Learn more, City name. Wind speed: meter/sec : meter/sec : miles/hour : deg: Wind direction : degrees (meteorological) degrees (meteorological) degrees (meteorological) gust: . dynamics in the Nepalese Himalaya, J. Geophys. All authors discussed the final form of the manuscript. The lowest wind component in the model output is at 10m above the surface, whereas the winds are observed at 5m height. Strong and shallow winds, resembling down-slope winds, are found on the leeward slope of the barrier followed by weaker and deeper winds at the valley entrance, 20km towards the valley from the barrier. Weather forecasts, nowcasts and history in a fast and elegant way. Thus, the decay of up-valley winds at this location is delayed by 3h compared with the other valleys. (without openweather) I added an outside temperature DHT22 via nrf24l01 (you are bme280) . https://doi.org/10.1175/1520-0450(1993)032<1669:TRBOSS>2.0.CO;2, 1993.a, b, Yang, K., Guyennon, N., Ouyang, L., Tian, L., Tartari, G., and Salerno, F.: the valley width increases) from the along-valley grid point 40 (xaxis in Fig.3b), at the valley floor elevation of 3000m, towards the valley top (along-valley grid point 0). 1. We've got answers. Overall, the model manages to simulate the diurnal cycle of the winds that was evident in the observations. You can place the following strings in your templates and when creating a new document using the template, they will automatically be replaced with the corresponding weather strings. Glaciol. Now in this section, we will see how to access weather data. That means accessing data for . The valley depth (the difference between the ridge and valley centre line heights) is lowest in the Gaurishankar Valley. The World is Not Flat: Implications for the Global Carbon Balance, Bull. I have configured the openweathermap add-on to get the current wind speed. Meteorol., 43, 170181, Invalid API-key errors might occur if your API key is used with the other modes. Translation is applied for the city name and description fields. Although the large-scale flow during the studied 4d period is similar to the 40-year climatology, the results are subject to uncertainty, due to the short simulation period, and may not be valid under different or more time-variable large-scale forcing. The simulation is evaluated using meteorological observations from three AWSs in the Khumbu Valley. pr-submitted The wind speed above this location, 200m higher than the model level that is shown in Fig.6, is already reduced by half (not shown). Openweather will add 40 to each donation and send it to Disastrous Emergency Committees (DEC) Ukrainian Humanitarian Appeal. Am. Headquarters in London, UK. The temperature difference causing the along-valley winds is explained by the valley volume effect (Whiteman,2000). One of the analysed locations, the middle of the top half of Kanchanjunga (red time series in Fig.7d), shows signs of a single circulation cell. Powered by Discourse, best viewed with JavaScript enabled, [openweathermap] How to get windspeed in km/h. There is currently support for the following device types within Home Assistant: You need an API key, which is free, but requires a registration. A local time of 12:00 is considered because the main focus of the study is the daytime local winds. The up-valley wind layer is deepest in the portion of the Makalu (grid points 120160) and Kanchanjunga (grid points 70120) valleys with a flat valley floor, where the flow depth reach up to 1500m, and shallowest at the top of the Gaurishankar (grid points 2040) and Khumbu (grid points 3050) valleys, where the flow depth is less than 600m. This would limit the reliability of the model simulation in the smallest sub-branches of the main valleys. The

Dommen, J.: Biogenic particles formed in the Himalaya as an important source An adaptive time step with a target CourantFriedrichsLewy value of 0.8 was used to keep the simulation numerically stable. Res.-Atmos., 126, 3, A sensor entity will be created for each supported condition. The large-scale flow is examined at 400hPa, as the surface pressure is below 500hPa at many locations within the study area. In this section you will learn how to access weather data for several cities. The outer domain covers an area of 36182997km and was run with a horizontal grid spacing of 27km. Hydrometeorol., 19, 15651581, https://doi.org/10.1175/JHM-D-17-0212.1, The key itself may take a couple of hours before it is activated. Part II: Implementation of a New Snow Parameterization, Mon. J. Accurate modelling of these thermally driven winds requires high horizontal resolution, down to at least a 1km grid spacing, due to their complex structure and sensitivity to the topography (Schmidli etal.,2018). Res., 18, 2330, 2001.. Global coverage, Email notifications, Track the main weather parameters: temperature, wind speed, precipitation. In the afternoon (20December at 15:00LT), the up-valley winds flow in the valley atmosphere all the way to the top of the valley (blue crosses in Fig.9) in all four valleys. We show that, regarding the daytime up-valley winds, the Khumbu Valley is not an exception compared to the other major valleys in this region. The night-time down-valley winds are found more during the large-scale northerlies, which is most likely due to channelling of above-valley winds into the valley atmosphere. In Khumbu Valley, the daytime up-valley winds have maximum respective values of 3, 5, 45 and 23ms1 at the four marked locations between 20 and 21December, listed from the valley entrance to the valley top (Fig.6b). Please add products before saving :). The Weather entity provides data only in English. Central Himalayas, J. Geophys. In this case, the API response should be returned in the same language as the language of requested location name if the location is in our predefined list of more than 200,000 locations. Kain, J.S.: The Kain-Fritsch Convective Parameterization: An Update, J. Along the leeward side of the barrier, between the plain and the Gaurishankar and Khumbu valleys, the isentropes descend and are parallel to the slope (Fig.9a, b). the lowest 1500m from the ground).

Using only one API call, you can get Forecast (for 10 days with 3-hour step), Historical, and Current weather maps. During the simulation period, the wind speed is weakest at the valley top and strongest in the middle of the valley (Fig.S4c and d in the Supplement). Their ids will follow the format: sensor._. Day-to-day variation in the along-valley winds is low, the along-valley wind speeds vary less than 2ms1 in each part of the valley, and the onset and offset of the up-valley winds vary by less than 1h during 1821December. In the Kanchanjunga Valley, the approximately constant increase continues until the valley top. Liu, Q., Chen, Y., Han, Y., Cucurull, L., Reynolds, R.W., Rutledge, G., and Res.-Atmos., 123, 1318613202. For example: Winds %wind-speed% Km/h^ with gusts up to %wind-gust% Km/h^, With wind gust data this will convert to: Winds 10 Km/h with gusts up to 20 Km/h, Without wind gust data this will convert to: Winds 10 Km/h (The gusts text surrounded by carets will be removed). and Land Surface Datasets, Atmosphere, 9, 196. It includes DNI, DHI and GHI indices for the Clear Sky and Cloudy Sky models. Such a Great Article!! Local time is shown on the xaxes. NCO-P and the Namche AWS are located in open areas, whereas the Lukla AWS is surrounded by trees, according to the station photos from http://geonetwork.evk2cnr.org, last access: 19December2022. A., Soci, C., Abdalla, S., Abellan, X., Balsamo, G., Bechtold, P., Biavati, 2. regional climate model across a Himalayan catchment, Atmos. The second aim is to identify notable differences between the four valleys in terms of their local wind systems. During night-time, the winds are around 2ms1 and are directed up-valley in the top half of the valley (grid points 25 and 45 in Fig.6a), and they are less than 1ms1 up- or down-valley in the lower half of the valley (grid points 70 and 95 in Fig.6a). Selecting a onecall forecast mode with the free tier leverages the One Call API, resulting in updates every 5 minutes and is recommended for both hourly and daily forecast.

After 60 grid points (approximately 60km) into the valley, the valley floors start to incline towards the valley top. Sci. Positive values indicate higher potential temperatures at 15:00LT than at 09:00LT. Nepal Climate Observatory-Pyramid (5079m), Atmos. This study focuses on along-valley winds during a carefully selected 4d period in December 2014 that is representative of the post-monsoon season. I want to convert this into text format - Stack Overflow I have wind direction data coming from OpenWeatherMap API, and the data is represented in 0 to 360 degrees.

Specifically, the floors of the Himalayan valleys studied here are steeply inclined and rise from less than 500ma.s.l. The surface topography is from United States Geological Survey with a horizontal resolution of 30arcsec (1km) and is shown for domains d01 and d04 in Fig.2a and b respectively. The 40-year average and the daily averages of the large-scale flow during the study period are shown in Fig.1. What are variables? OpenWeather products are all ready-to-use and allow to minimise customers . In contrast, in the Makalu and Kanchanjunga valleys, the plain-to-valley winds flow in layers as deep as 10001500m. This is consistent with the stronger up-valley winds at this time in Kanchanjunga compared with the other valleys. If you do not see some of the parameters in your API response it means that these weather phenomena are just not happened for the time of measurement for the city or location chosen. In Makalu Valley, the valley floor elevation increases from 500 to 4000ma.s.l. resolution on WRF v3.8.1 simulated meteorology over the central Himalaya, So follow this till the end. In general, numerical weather prediction models require a spin-up period to allow the model to adjust from the specified initial conditions to a balanced state that is consistent with the models' own dynamics and physics. Synoptic-Scale Flows and Winds within a Valley, J. Appl. The rain has suspended play on outdoor courts for hours. Question 1: In all four valleys, the strongest up-valley winds occur at the entrances of the Makalu and Kanchanjunga valleys and 30km into the Gaurishankar Valley (around along-valley grid point 70).
