Bonekamp, P., Collier, E., and Immerzeel, W.: The Impact of Spatial Resolution, The plain-to-valley winds flow over the 1000m high barrier at the entrances to the Gaurishankar and Khumbu valleys in a shallow layer of less than 500m (grid points 110130 in Gaurishankar and grid points 120140 in Khumbu). A heat policy was first implemented in the 1998 Australian Open. Cross-valley width at an elevation of 1000m above the valley centre line is shown using the blue line. In this,JSON returns data from cities laid within definite circle that is specified by center point (lat, lon) and expected number of cities (cnt) around this point. The up-valley wind propagation into the valley could be significantly interrupted by the flow forced to flow over the 1km high barrier. The flow characteristics over this barrier are similar to what Stull (1988) describes with respect to the down-slope wind storms associated with hydraulic jump. The mean of the two ridge heights is shown by the black dashed lines. Although the large-scale flow during the 4d period was similar to the long-term climatology, the impact of different large-scale flows on the thermally driven winds was not considered. 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. and Dhaka, S.K.: Impact of Mountainous Topography on Surface-Layer Rozum, I., Vamborg, F., Villaume, S., and Thpaut, J.-N.: The ERA5 global Two of the valleys have a 1km high barrier in their entrances between the valley and the plain.

We now attempt to understand the differences in the daytime up-valley winds during this 4d period between the four valleys and along the individual valleys and to relate these differences to the differences in the valley topographies. FB helped with accessing the observational data and with planning the analysis. Whiteman, C.D. and Doran, J.C.: The Relationship between Overlying 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.

OpenWeather is a team of IT experts and data scientists that has been practising deep weather data science. A., Soci, C., Abdalla, S., Abellan, X., Balsamo, G., Bechtold, P., Biavati, 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). the unified NOAH land surface model in the WRF model, 20th conference on Specifically, the floors of the Himalayan valleys studied here are steeply inclined and rise from less than 500ma.s.l. The local narrowing of the valley topography accelerates the wind speed through this gap, assuming a constant along-valley mass flux on both sides of the narrowing part. These locations are shown by crosses in Figs.2b and 3, and the colours refer to the along-valley wind time series in Fig.6. List of all API parameters with available units. Keeley, S., Laloyaux, P., Lopez, P., Lupu, C., Radnoti, G., deRosnay, P., resolution on WRF v3.8.1 simulated meteorology over the central Himalaya, So you just need to put the units in your label to display it properly. In the morning (20December at 09:00LT), the potential temperature difference between the valley atmosphere and the plain is small in the layer where the up-valley winds flow (Fig.8). However, the local valley wind systems in the other major valleys located nearby have not yet been well studied. Direct link to signup page https://home.openweathermap.org/users/sign_up. Meteorol. The high wind speeds caused by the channelling are shown in the Supplement (Fig.S2). In the Makalu and Kanchanjunga valleys, the wind speed is up to 4ms1, and the flow depth is 10001500m above the valley centre lines. That means you can pass more than one city ID at one time. However, the cross-valley winds shown in Fig.7 are not the pure slope wind circulation, as the gradient of the slope elevation is not necessarily aligned perpendicularly to the valley centre line.

At the lowest model level (approximately 25m above the surface; Fig.11a, b, c, d), the diurnal cycle has a larger amplitude over the plain (up to 8K) than in the valleys (46K), but the amplitude decreases rapidly with height over the plain. Positive values indicate higher potential temperatures at 15:00LT than at 09:00LT. Chem. 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). floor inclination, width, depth and valley cross-section narrowing) on thermally driven flows using idealised numerical simulations. Unlike in the other three valleys, the valley floor in the Kanchanjunga Valley only starts to incline strongly close to the top of the valley, and the near-surface warming reaches further into the Kanchanjunga Valley compared with the other three valleys. The period of this case study was selected to coincide with the measurement campaign by Bianchi etal. I have configured the openweathermap add-on to get the current wind speed. https://doi.org/10.1093/oso/9780195132717.001.0001, 2000.a, b, c, d, Whiteman, C.D. and Doran, J.C.: The Relationship between Overlying The land surface scheme used in the simulation was the Unified Noah land surface model (Tewari etal.,2004).

The black star, blue cross, and red cross on the yellow line show the locations of the Nepal Climate Observatory Pyramid (NCO-P) station, the Namche AWS and the Lukla AWS respectively. As discussed in Sect.4.2, the daytime plain-to-valley winds cross this barrier in a shallow layer of a few hundred metres. Figure3 gives an overview of the topographic characteristics along each of the four valleys based on the diagnostics defined in Sect.2.3.1. The yellow lines in Fig.2b were manually extended from the valley entrance to reach over the adjacent plain. Res.-Atmos., 126, 3. Chem. The elevation of 1000m above the valley centre line was chosen based on the valley depths; most of the valleys have a minimum depth of 1000m (valley topographies are described in detail in Sect.3). Please note that built-in geocoder functionality has been deprecated. To compare the modelled values to the observations, model variables were taken from the closest model grid point. However, Collier and Immerzeel (2015) suggested that their WRF simulation with a 1km horizontal grid spacing was not accurate enough to fully resolve the thermally driven valley circulations in the narrowest parts (length scales of less than 2km) of the Langtang Catchment (located just outside our innermost WRF domain to the west). The standard deviation of the 40-year monthly means is shown by the black contours (ms1). Today we have more than 80,000 weather stations around the world. Enhance your short-term planning with Road Risk API by exploiting an accurate minute-by-minute forecast for 2 hours, hourly weather forecast and national alerts for five-days. These two group of valleys can be separated by their topographical characteristics: the valleys in the west have a continuous inclination in the valley floor, and there is a 1km high perpendicular mountain barrier between the valley entrance and the plain; the valleys in the east have a 40 (Makalu) and 60km (Kanchanjunga) portion with a flat valley floor from the open valley entrance into the valley.

Well-defined daytime up-valley winds are simulated in all of the valleys with some variation in the flow depth and strength among the valleys and their parts. Bollasina etal. Glaciol. Keep Rocking!! Am. Glaciol. Therefore, in this study, we do not attempt to provide a climatology of the thermally driven winds. JM performed the data analysis and wrote most of the paper with input from VS. VS performed the WRF simulation and helped with planning the analysis. I have used these in my own application to convert a JSON response of: 1 2 3 4 "wind": { "speed": 5.7, "deg": 50 }, into: Wind speed: 12.75 mph in a North East direction. OpenWeather is a team of IT experts and data scientists that has been practising deep weather data science since 2014. This would limit the reliability of the model simulation in the smallest sub-branches of the main valleys. The World is Not Flat: Implications for the Global Carbon Balance, Bull. Manage deliveries with confidence by using tools that help you route accordingly. OpenWeather. 25072522. 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. Weather The mean of the two ridge heights is shown by the black dashed lines. Figure1(a) The 400hPa wind speed (shading) and direction (white vectors) averaged over the month of December for the period from 1980 to 2019 in the ERA5 reanalysis. Sci., 67, 37393756, https://doi.org/10.1175/2010JAS3428.1, The xaxes show the deviation from the 2d mean potential temperature of that model level in each grid point located on the valley centre line. The along-valley wind component is calculated based on Eq.(4) for four different parts of each valley. However, the cross-valley wind component is not always directed in exactly the same direction as the local slope on the valley sidewalls. Laj, P., Lehtipalo, K., Kangasluoma, J., Kerminen, V., Kontkanen, J., Push notification mechanism will allow to get timely notifications about severe weather. Weather Rev., 122, 927945, The data are plotted every 30min. Bonaf, U., Calzolari, F., Colombo, T., Decesari, S., DiBiagio, C., The Stack Overflow answers here and here that helped me understand how to convert wind direction to compass points. Please note that built-in geocoder functionality has been deprecated. 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). To use openweathermap API, you need to create an account in their site. The jet seen in the 40-year average (Fig.1a) is much wider than in any of the daily averages, suggesting that the exact latitudinal position of the jet varies from day to day. The horizontal grid spacing decreases to 9km (d02), 3km (d03) and finally to 1km in the innermost domain, which covers an area of 288300km. The simulation was kept on track by nudging the temperature, horizontal wind components and specific humidity in the outer domain (d01) towards the reanalysis every 6h. Positive values for the cross-valley wind component on both slopes refer to up-slope winds. Figure4 shows the 400hPa wind in the outer domain (d01) in the WRF simulation at 12:00LT (noon) on 1821December2014. 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 To do this, we relate our results to previous studies that have used highly controlled idealised simulations to quantify the impact of valley geometry on valley winds. 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.
