3.1.2.4. Evaluation of tourism exploitation time criteria

The time for tourism exploitation is determined by the number of favorable days for tourism activities in a year and the number of days with the most suitable climate conditions for human health. (Weather data used for calculation is the average of 10 years, 2009 - 2018 - Appendix 2).

a. Evaluate the number of favorable days for tourism activities

* The number of favorable days for tourism is the number of days in a year (365 days) minus the days with unfavorable weather for tourism (including rainy days, stormy days, strong southwest wind days, foggy days, and stormy days). Determining unfavorable weather days for tourism is determined as follows:

- Number of rainy days and stormy rains: The rain in Phu Yen province is mainly due to tropical convergence and rain due to the influence of storms or tropical depressions, so the rain often occurs with high intensity, high water concentration and each rain period usually lasts from 03-05 days. With the type of rain with high water concentration, the average rainfall of 20mm/day will affect tourism activities. Therefore, the number of rainy days is determined to be unfavorable for tourism in Phu Yen territory is the day with an average rainfall of over 20mm.

- Number of stormy days: Stormy days in Phu Yen often occur in summer and autumn and winter. However, autumn and winter (from September) is the rainy season in Phu Yen, so stormy days are often accompanied by rain (seasonal transition), these days have been counted in the number of unfavorable days due to rain, so the calculation of the number of stormy days unfavorable for tourism is calculated before August.

- Number of days with strong dry and hot westerly winds: The strong dry and hot indicator is the absolute maximum daily temperature ≥37 o C, combined with the lowest relative humidity during the day ≤45%.

* The data used for calculation is the 10-year average data (from 2009 to 2018) of rain gauges and meteorological stations in Phu Yen province. The results of the observation stations near the observation stations will be used for calculation. The number of rain gauge stations in Phu Yen province is relatively densely distributed, so the calculation results of the number of rainy days of the rain gauge stations are highly accurate. The rain gauge stations used for calculation include Tuy Hoa, Phu Lac, Song Cau, Son Thanh, Ha Bang, Son Hoa.


However, for meteorological data (number of stormy days, strong foehn winds, fog), the calculation results are taken from two meteorological stations: Son Hoa station (used for TNTN points distributed in the West) and Tuy Hoa station (used for TNTN points distributed in the East), because Phu Yen province only has these two meteorological stations. The observation results of these two stations can be used to calculate for 17 TNTN points in the thesis for the following reasons:

- Phu Yen's territory is not large, the shape of the territory is generally balanced (87km long, about 72km widest place), the terrain is relatively clearly divided: the East is low plain terrain interspersed with hills and mountains; the West is hills, low mountains and plateaus. That is what creates the main climate differentiation according to the two mountainous regions in the West and the coastal region in the East, within the region the climate is not clearly differentiated.

- For the TNTN points in the eastern coastal area, the TNTN point selected for evaluation is located furthest from Tuy Hoa meteorological station, which is Tu Nham beach - Vinh Hoa (about 43km). As for the TNTN points selected for evaluation in the west, the resource point located furthest from Son Hoa station is Triem Duc mineral spring (more than 30km from the station). Thus, using data from 2 meteorological stations to calculate for TNTN points is appropriate (because according to regulations, the allowable accuracy is within a radius of 50km from the monitoring point).

- According to the interview results with experts at Tuy Hoa Hydrometeorological Station, meteorological observation data from Tuy Hoa and Son Hoa stations are used to calculate and forecast weather phenomena in the plains and mountainous areas of Phu Yen with high accuracy (over 80%). Therefore, data from these two stations are also used to calculate tourism development in the thesis.

The results of the evaluation of the number of favorable days for tourism activities by year are shown in Table 3.7.

b. Evaluate the number of days with climate suitable for human health

The number of days with a climate suitable for human health is calculated based on the average absolute humidity and average monthly temperature (Table 3.5 and Table 3.6), shown on the temperature-humidity diagram (Figures 3.7 and 3.8).

* Results of analysis of the temperature - humidity correlation diagram of Tuy Hoa station (Figure 3.7) show


- The months of December; January; February; March on the diagram are in the hot zone, with the lowest temperature.

Average 21.1 o C (January), average maximum temperature is 29.8 o C (March), no day has temperature above 33 o C. On the background of typical tropical monsoon climate, high temperature (average annual temperature 26 o C), no cold winter, so the above climate conditions for Phu Yen are considered pleasant, suitable for human health. Thus, the number of days with climate suitable for human health is 121 days. Compared with the research results on heat index suitable for human health by authors: Pham Ngoc Toan - Phan Tat Dac, Indian scientists is suitable [Appendix 3].

- The number of days with climate unsuitable for human health is 244 days (the remaining months, located in the hot zone on the diagram).
