Measurement of Temperature, Humidity, and Wind Speed and
Direction
Introduction:
According to National Geographic, temperature is a measurement of the
heat or coolness of a thing and is measured in degrees Celsius or
Fahrenheit, and humidity is defined as the totality of the water vapor that
rises in the air, if the water vapors are many, then the humidity will
increase, so if the humidity is high, then it will feel wet outside. Following
the blog of Windy.app, wind speed is defined as the distance that has
been covered by the air in a particular time, and the wind direction will
always be ascertainable by where it originates.
All of the Temperature, Humidity, Wind Speed and Wind Direction are
interconnected towards each other. These are the factors that formed the
weather patterns and atmospheric conditions. Temperature does affect
the Air pressure because warm air is lighter and moves upwards, thus
creating lower pressure zones, whereas cold air is heavy, resulting in the
formation of high-pressure zones. Furthermore, these pressure differences
are responsible for winds blowing from high to low-pressure areas, thus
affecting the speed and direction of wind. The amount of moisture
contained in the air or humidity is directly related to temperature; warmer
airs hold more water vapor, resulting in high levels of humidity, while
colder airs have less. However, humidity levels can be altered by
changing temperatures, while winds can bring either wet or dry air,
influencing local humidity. Their velocity depends on how strong the
difference between two places’ air pressures is—the greater the variation
in air pressure, the faster the winds can blow—carrying along air particles
possessing dissimilar heat contents and wetness. Their velocity depends
on how strong the difference between two places’ air pressures is—
greater pressure differences cause faster movement of air masses with
different temperatures and moisture content. Such winds carry differently
heated and hydrated air parcels; for example, wind coming from oceans
usually carries cooler and moist air, but more hot and dry winds are from
land or deserts. Therefore, all these have an impact on dynamic and
changeable weather patterns, including temperature, which affects
humidity's response to it, influencing the rate of change rate and making
complex systems more variable over time.
The importance and purpose of this laboratory activity is to expand our
knowledge in understanding the local weather patterns by directly and
individually monitoring the key environmental factors such as
temperature, humidity, wind speed, and direction. By collecting and
monitoring the data, students can observe how these key factors interact
and change over the day. This seven-day straight collection of data will
lend us the experience to improve and appreciate the meteorological
concepts more.

Objectives:
1. To be able to measure and observe air temperature for 7 days using a
mercury thermometer.
2. To be able to measure and observe air humidity for 7 days using a
hygrometer or any available device.
3. To be able to identify and observe wind velocity and direction for 7
days using an anemometer and wind vane or any available device.
Materials Used:
I utilized the following materials during the laboratory study:
• A hygrometer
• A smartphone to access weather updates online
Methodology:
To make sure that the data I have gathered regarding the measurements
of temperature, humidity, wind velocity, and direction are accurate. Steps
are followed to start this laboratory. First, I have gathered the materials
needed in this activity, which are the hygrometer that I will be using to
measure the temperature and humidity percentage and the smartphone
in which I can access an online application that will tell the weather at that
current moment for me to acquire data regarding the wind velocity and
direction. Second, with the use of all the materials, I will be monitoring the
changes in temperature and humidity, including the wind direction, every
day for seven days straight. I took readings three specific times a day with
a time gap at 8:00 in the morning, 12:00 noon, and 6:00 in the evening,
but sometimes they were not accurately followed due to some important
matters. Lastly, I was able to acquire the data needed and document the
measurements from September 18 to September 24, 2024. However, the
differences in measurements may vary depending on the humidity of the
data from the online weather application and the hygrometer and
concerning the online weather update, it was in miles per hour, so I
converted it to kilometers per hour.

According to the weather data I have gathered during September 18 to
24, 2024 in Brgy Kiagot, Digos City, Davao del Sur. There are several
happenings that can be observed regarding the temperature, humidity,
wind velocity, and overall weather conditions. Over the 7 days, the
weather mostly involved warm to hot temperature with diverse levels of
humidity and intermittent rain. The dry bulb temperature ranged from
29.8°C to 35.9°C, indicating continuously warm weather, with the
maximum temperatures typically occurring in the late afternoon or early
evening. The wet bulb temperature, which reflects the cooling influence of
moisture in the air, fluctuated less, ranging between 26.2°C and 31.8°C.
The relative humidity ranged between 59% and 98%, with higher humidity
frequently occurring in the mornings and nights, especially when rain or
an overcast sky was present.
Wind speeds were generally light all through this time, ranging from
3.2 kph to 11.2 kph and coming primarily from the east and southeast.
While these wind speeds may have provided some relief from the heat,
they were insufficient to dramatically change the local weather conditions.
On numerous days, the data indicates a clear transition from sunny or
clear skies in the morning to cloudier conditions or rain in the evening. For
example, on September 19, the day began sunny and finished with severe
rain in the evening. Similarly, September 24 began with significantly
cooler and cloudier weather, followed by a clear midday and heavy rain
later in the evening. These shifts point to the presence of localized
convection and typical tropical weather patterns, in which daytime
warmth frequently leads to nighttime rains.
In summary, the data indicates a complicated interaction between
temperature and humidity. While high temperatures at noon are
frequently associated with lower humidity levels (as shown on September
20 and 23), there are times when high temperatures coexist with high
humidity, notably after rain or during gloomy conditions. This implies that,
while temperature and humidity might behave inversely under some
situations, such as clear, bright weather, their connection is not simple.
Moisture in the atmosphere, local weather systems, and rainfall may all
have an impact on how temperature and humidity interact, resulting in
both high-temperature, high-humidity conditions and the more common
high-temperature, low-humidity patterns.

Conclusion:
In conclusion, the weather data from Brgy. Kiagot Digos City over the
seven days shows the typical tropical weather conditions characterized by
high temperatures, high humidity, light to moderate winds, and variable
cloud cover and rainfall. The winds supplied little relief because of their
relatively low speeds. The mix of high temperature and high humidity
during the day would have led to a hot and uncomfortable environment,
specifically in the afternoons. In the data given, it is observed that there is
a pattern of evening rainfall following sunny days that is consistent with
the behavior of tropical climates, where convection often leads to rain
later in the day.

9. Based on your laboratory data, can you say that temperature is
inversely proportional to the humidity? Explain your answer.
- I cannot conclude that temperature is inversely proportional to
humidity based on the laboratory data. Although there are times
when a rise in temperature and a fall in relative humidity are
related, this link is not constant across the data. For instance, there
appears to be an inverse link between humidity and temperature
because it tends to be lower at midday on days with high
temperatures, like September 18 and 20. On some occasions,
though, high humidity and temperatures coexist simultaneously.
One such instance is midday on September 22, when the humidity
was 82% and the temperature was 35.3°C. This indicates that
reduced humidity is not necessarily a result of high temperatures,
particularly in areas with a lot of air moisture. It would be correct to
say that temperature and humidity are exactly inversely
proportional because their interaction is indeed inversely
proportional towards each other but in this data, it is more
complicated and impacted by other elements such as atmospheric
moisture and weather patterns, even if they can occasionally show
an inverse relationship.
