Select The Correct Locations On The Table.A Snowstorm Was Predicted In Chicago. Identify The Possible Upper Air Temperature, Surface Temperature, And Air Pressure Of Chicago On That Day. Normal Atmospheric Pressure Is 29.9 Inches Of
Introduction
Chicago, a major city in the United States, is known for its diverse climate, which can range from hot summers to cold winters. In this article, we will explore the possible atmospheric conditions in Chicago on a day when a snowstorm is predicted. We will examine the upper air temperature, surface temperature, and air pressure of the city on that day.
Atmospheric Pressure
Atmospheric pressure is the force exerted by the weight of the air in the atmosphere. It is measured in inches of mercury (inHg) or millibars (mb). Normal atmospheric pressure is 29.9 inches of mercury (inHg) or 1013 millibars (mb). However, atmospheric pressure can vary depending on the location and weather conditions.
Surface Temperature
Surface temperature is the temperature of the air at the surface of the Earth. It is influenced by the amount of solar radiation the area receives, as well as the presence of clouds and other weather conditions. In Chicago, the surface temperature can range from -20°F (-29°C) in winter to 90°F (32°C) in summer.
Upper Air Temperature
Upper air temperature refers to the temperature of the air at higher altitudes. It is influenced by the movement of air masses and the presence of weather systems such as high and low-pressure systems. In Chicago, the upper air temperature can range from -50°F (-45°C) in winter to 50°F (10°C) in summer.
Predicting Atmospheric Conditions
To predict the atmospheric conditions in Chicago on a day when a snowstorm is predicted, we need to consider the following factors:
- Weather patterns: A snowstorm is predicted, which means that a low-pressure system is likely to be present over the area.
- Temperature: The surface temperature is likely to be below freezing, which is necessary for snow to form.
- Humidity: The air is likely to be humid, which is necessary for snow to form.
Possible Atmospheric Conditions
Based on the above factors, the possible atmospheric conditions in Chicago on a day when a snowstorm is predicted are:
- Surface temperature: 25°F (-4°C) to 30°F (-1°C)
- Upper air temperature: -20°F (-29°C) to -10°F (-23°C)
- Atmospheric pressure: 29.5 inHg (1000 mb) to 30.5 inHg (1030 mb)
Conclusion
In conclusion, the possible atmospheric conditions in Chicago on a day when a snowstorm is predicted are a surface temperature of 25°F (-4°C) to 30°F (-1°C), an upper air temperature of -20°F (-29°C) to -10°F (-23°C), and an atmospheric pressure of 29.5 inHg (1000 mb) to 30.5 inHg (1030 mb). These conditions are necessary for a snowstorm to occur and are influenced by the presence of a low-pressure system, below-freezing temperatures, and humid air.

Table of Possible Atmospheric Conditions
| Surface Temperature | Upper Air Temperature | Atmospheric Pressure |
|---|---|---|
| 25°F (-4°C) to 30°F (-1°C) | -20°F (-29°C) to -10°F (-23°C) | 29.5 inHg (1000 mb) to 30.5 inHg (1030 mb) |
Discussion
The table above shows the possible atmospheric conditions in Chicago on a day when a snowstorm is predicted. The surface temperature is likely to be below freezing, which is necessary for snow to form. The upper air temperature is also likely to be below freezing, which is necessary for snow to form. The atmospheric pressure is likely to be lower than normal, which is necessary for a low-pressure system to be present over the area.
Conclusion
Q: What is the normal atmospheric pressure in Chicago?
A: The normal atmospheric pressure in Chicago is 29.9 inches of mercury (inHg) or 1013 millibars (mb).
Q: What is the surface temperature in Chicago during a snowstorm?
A: The surface temperature in Chicago during a snowstorm is likely to be below freezing, ranging from 25°F (-4°C) to 30°F (-1°C).
Q: What is the upper air temperature in Chicago during a snowstorm?
A: The upper air temperature in Chicago during a snowstorm is likely to be below freezing, ranging from -20°F (-29°C) to -10°F (-23°C).
Q: What is the atmospheric pressure in Chicago during a snowstorm?
A: The atmospheric pressure in Chicago during a snowstorm is likely to be lower than normal, ranging from 29.5 inHg (1000 mb) to 30.5 inHg (1030 mb).
Q: What are the necessary conditions for a snowstorm to occur in Chicago?
A: The necessary conditions for a snowstorm to occur in Chicago are:
- A low-pressure system over the area
- Below-freezing temperatures
- Humid air
Q: What is the role of a low-pressure system in a snowstorm?
A: A low-pressure system is necessary for a snowstorm to occur. It brings cold air from higher latitudes and creates the necessary conditions for snow to form.
Q: What is the role of humidity in a snowstorm?
A: Humidity is necessary for snow to form. When the air is humid, it can hold more moisture, which can then freeze into snow.
Q: What is the role of temperature in a snowstorm?
A: Temperature is necessary for snow to form. When the temperature is below freezing, the moisture in the air can freeze into snow.
Q: Can a snowstorm occur in Chicago without a low-pressure system?
A: No, a snowstorm cannot occur in Chicago without a low-pressure system. The low-pressure system is necessary to bring the cold air and create the necessary conditions for snow to form.
Q: Can a snowstorm occur in Chicago without humid air?
A: No, a snowstorm cannot occur in Chicago without humid air. The humid air is necessary to hold the moisture that can then freeze into snow.
Q: Can a snowstorm occur in Chicago without below-freezing temperatures?
A: No, a snowstorm cannot occur in Chicago without below-freezing temperatures. The below-freezing temperatures are necessary for the moisture in the air to freeze into snow.
Conclusion
In conclusion, the atmospheric conditions in Chicago during a snowstorm are a surface temperature of 25°F (-4°C) to 30°F (-1°C), an upper air temperature of -20°F (-29°C) to -10°F (-23°C), and an atmospheric pressure of 29.5 inHg (1000 mb) to 30.5 inHg (1030 mb). These conditions are necessary for a snowstorm to occur and are influenced by the presence of a low-pressure system, below-freezing temperatures, and humid air.
