SLC S22W6: Interpretation of weather radar images

_{Edited by canva}

Go to one of the weather forecasting sites mentioned in class (WeaWow or AccuWeather)

To answer the first question, I chose the WeaWow application to consult the weather forecast, my choice fell on this application because of its clear interface, its advanced features and the absence of advertisements, this which makes the user experience pleasant and fluid, from my smartphone I accessed the Google Play Store, searched for WeaWow and installed it, once the application was downloaded, I opened it from its icon present in the menu main of my device.

The application offers detailed and personalized forecasts based on my current location, here Oued Ellil, it displays in real time information such as the temperature, which was 12°C, as well as weather conditions indicating clear skies, j I also explored hourly and daily forecasts, which specify maximum and minimum temperatures and their evolution throughout the day.

Check the current weather conditions. Does it match reality? (Show a photo)

Indeed, I examined the current weather conditions using the WeaWow application and compared this data to the observed reality and here is a complete analysis:

Parameter	WeaWow data	Actual observation
Current temperature	11°C	Consistent with the sensation on site
Feels like temperature	9°C	Corresponds to the actual sensation of freshness
Cloud cover	0 %	The sky is completely clear (photo in support)
Precipitation	0 mm	No rain observed
Wind speed	7 km/h (southwest)	Light wind felt on site
Humidity	90 %	Consistent with slightly humid air
Atmospheric pressure	1019 hPa	Consistent with a stable and calm evening
UV index	0	Night, therefore no UV radiation
Weather map	No visible precipitation or turbulence	Reality confirmed by local observation

Analysis of results

The data provided by WeaWow is very precise and corresponds perfectly to field observations, the photo shows a clear sky, confirming the absence of clouds or precipitation, the temperature felt reflects the perceived freshness, and the others parameters, such as humidity and wind speed, also correspond to the sensations and conditions observed, the application, by providing an interactive map of winds and precipitation, further enriches the accuracy of the forecasts, making it possible to check regional conditions, this reinforces the reliability of WeaWow as meteorological tool.

Check the trends/forecasts shown by the app and interpret what you see there (Variables: Precipitation, temperature and pressure)

To interpret the trends and forecasts provided by the WeaWow application regarding precipitation, temperature and pressure variables, here is a complete analysis based on interactive map data:

Precipitation

The precipitation map indicates areas of varying intensity near Le Kef on February 1st, with colors ranging from green (light precipitation) to red (heavy precipitation), at the Tunis site, no precipitation is expected , after adjusting the play button to view the hourly forecast, the map confirms an absence of precipitation in Tunis for the next few hours, this indicates dry weather in this area, while some neighboring regions could experience heavy rain.

Temperature

The temperature forecast shows a gradient map, going from light yellow (moderate temperatures) to bright red (high temperatures), in Tunis the temperature is stable around 13.9°C, reflecting a relatively cool climate , in comparison, the interior regions of the country show slightly lower temperatures, while coastal areas like Gabès remain moderately warm, these variations can be explained by the proximity of the sea and the moving air masses.

Pressure

The pressure map indicates stable ground pressure around 1012 hPa in Tunis, suggesting calm and stable weather conditions, areas with lower pressures, such as those located northwest of Tunis, could be associated to weather disturbances or instability in the coming days, conversely, higher pressures towards the interior of the country suggest drier and clearer weather.

Summary

The data shows calm weather in Tunis, with no precipitation expected in the short term, with a moderate temperature and stable pressure, these conditions reflect a peaceful and pleasant environment for the coming hours, with a probability of dry and clear weather, the forecast for neighboring regions, however, suggest marked variations, particularly in terms of precipitation and temperature.

Based on what you reviewed and what you have learned... IN YOUR OPINION: Do you think weather forecasting apps are accurate or not? Explain why.

According to my analysis of the WeaWow application, weather forecast applications are generally reliable, especially for short-term forecasts, they provide detailed and updated information in real time, such as temperature, precipitation, speed of the wind and humidity which often correspond to observed conditions, this data, presented clearly using interactive maps and graphs allows you to better understand weather trends and effectively plan daily activities.

However, their reliability decreases when it comes to long-term forecasts, generally beyond three to five days. This drop in accuracy is explained by the unpredictable nature of the atmosphere and the limitations of current weather models, moreover, these applications do not always take into account local variations, such as microclimates or sudden changes, particularly in remote areas or areas poorly covered by weather stations; the quality of the forecasts also depends on the density and precision of the forecasts data available in a given region.

In conclusion, applications like WeaWow are practical and reliable tools for daily use or short term planning, however they should not be used as the sole source of information for important decisions or in situations requiring high precision, in these cases it is recommended to complement these forecasts with other reliable sources or expert opinions.

Based on the information in the app, dare to give a weather forecast for the next few hours.

Region	Temperature (°C)	Pressure (hPa)	Humidity (%)	Wind (km/h) (Direction)	Conditions
Tunis	11.9	1017	76	4 (Calm, direction 0°)	Cool weather, clear or partly cloudy skies. Moderate humidity. No rain expected.
Gabès	16.0	1023	86	15 (NNW - North-Northwest)	Slightly warmer, clear skies. Moderate wind from the northwest. High humidity.
Sfax	~13-15 (estimated)	~1017-1023 (estimated)	78-82 (estimated)	~5-10 (light to moderate)	Conditions similar to Gabès. Stable, slightly humid, with light to moderate winds.
Annaba (Algeria)	~12-14 (estimated)	~1015 (estimated)	~75-80 (estimated)	~10-15 (wind NNW)	Cool conditions, moderate wind from the north.

Temperatures:

• Temperatures vary between 11.9°C (Tunis) and 16.0°C (Gabes), which is typical of a cool night or evening.
• No drastic drop expected in the next few hours.

Atmospheric Pressure:

• Pressure is relatively high, between 1017 hPa and 1023 hPa, indicating atmospheric stability. This means that no disruptive weather events (such as storms) are expected.

Humidity :

• Humidity ranges from 76% to 86%, which can create a feeling of dampness in the air, especially in areas such as Gabès.
• This humidity is not expected to cause immediate precipitation, but coastal areas may experience haze.

Wind :

• Winds remain light to moderate, between 4 km/h and 15 km/h, mainly oriented towards the north-northwest (NNW).
• Light winds around Tunis suggest a calm evening without gusts.

General Conditions :

• No precipitation is expected.
• The sky will be clear to partly cloudy, with a stable atmosphere and cool temperatures.
