Dew point and humidity: What’s the difference?

Dewpoint and Relative Humidity

Relative humidity and dew point are often mistaken for the same thing, and can be sources of confusion. We have recently gotten questions about the differences between the two, and which is more relevant in everyday life.

 

Relative humidity and dew point both give us an idea of the amount of moisture in the atmosphere; however only dew point is a true measurement of the atmospheric moisture.

 

Relative humidity is defined by the National Weather Service as the amount of atmospheric moisture present, relative to the amount that would be present if the air were saturated. But what does that really mean? In short, the relative humidity is a function of both the moisture content in the atmosphere and the actual air temperature. By itself, it does not directly indicate the amount of moisture present in the atmosphere.

 

Relative humidity is calculated using meteorological variables such as vapor pressure, saturation vapor pressure, temperature and dew point. Without explaining the equation variable by variable, we can simply state that the relative humidity is determined by how close the air temperature is to the dew point temperature. The closer these values are, the higher the humidity. The further apart these values are, the lower the humidity.

 
Dew point is the term that most meteorologists use to describe the amount of moisture in the air. The National Weather Service defines dew point as the temperature to which air must be cooled to in order to reach saturation, assuming air pressure and moisture content are constant. In short, the dew point is an accurate measurement of the moisture content in the air. When talking about a certain day feeling “muggy” or “sticky,” the dew point temperature is the more accurate term to use.

Vice President Mike Pence was ready for a secret meeting with North Korean officials at the 2018 Winter Olympics in Pyeongchang, South Korea, earlier this month, but the North backed out, according to news outlets.

Pence attended the Olympics Opening Ceremony on Feb. 9 as part of a five-day trip to Asia and was seated near Kim Jong-un’s sister, but did not speak to her, creating a media sensation.

The North canceled the meeting just two hours before Pence was scheduled to meet with Kim Jong-un’s sister, Kim Yo Jong, and another North Korean state official, Kim Yong Nam, on Feb. 10 after Pence announced new sanctions against the North Korean regime during his trip and rebuked it for its nuclear program, according to the Washington Post, which was the first to report on the secret meeting.

“North Korea dangled a meeting in hopes of the vice president softening his message, which would have ceded the world stage for their propaganda during the Olympics,” the vice president’s chief of staff, Nick Ayers, said in a statement, according to The Hill.

News of the secret meeting comes as relations between the communist north and democratic south seem to be thawing in recent weeks with the announcement last month from Kim Jong-un that he was sending a delegation to the Olympics. He sent his sister to lead the group.

“We regret [the North Koreans'] failure to seize this opportunity," State Department spokesperson Heather Nauert said in a statement. "We will not apologize for American values, for calling attention to human rights abuses, or for mourning a young American’s unjust death."

Dayton residents, leaders urge DPS board not to close schools

Residents, union officials and community leaders spoke out at Dayton’s school board meeting Tuesday night, telling the board that they oppose any plan to close schools, just hours after the task force studying that issue wrapped up its last formal meeting.

Brian “Mr. U” Urquhart, a retired DPS teacher and coach who still subs in the district, joked that Presidents Day was fitting for a discussion of school closings, since the district has over the years closed schools named Washington, Lincoln, Jefferson and Roosevelt.

Urquhart urged school board members to look at four factors when considering whether to close a school — test data, attendance figures, discipline/suspension rates, and teacher dissatisfaction via transfers.

Steve Keeney, who represents the district’s AFSCME unions for custodial, security and other employees, said employees are concerned that words like right-sizing and fiscal accountability often turn into layoff plans.

Keeney said the district should be looking not just at expenses, but also at the revenue side — lobbying state government about funding, pushing back against tax abatements and considering a levy if more than short-term fixes are needed.

Jamica Garrison, a leader of the Neighborhoods over Politics group, asked board members to put themselves in the shoes of students who would be affected by school closings, saying she herself had to attend multiple Dayton elementary schools in six years.

She said students end up with doubts about making new friends or getting support from teachers who don’t know them. She also pushed DPS to more aggressively market the schools’ successes to increase enrollment.

Earlier in the day, DPS task force co-chair Jeff Mims had made a similar comment about working to increase enrollment, saying DPS needs to do exit interviews with families that leave the district to understand exactly what it would take to get them back.

Longtime teacher Kimaru Wa-Tenza told the school board Tuesday night that the idea of closing or repurposing newer schools when residents are still paying off their construction via taxes is “a little hard for the average citizen to take.”

Since DPS officials have often mentioned fiscal responsibility issues, Wa-Tenza asked where that responsibility had been in the buyouts of administrators David Lawrence and Rhonda Corr, the issuing of a new contract for athletic director Mark Baker after the OHSAA sanctioned the district.

Derrick Foward, president of the Dayton Unit NAACP repeated his group’s desire to keep all schools open and give students the ability to attend schools in their neighborhoods. After a few speakers had questioned the term “right-sizing,” Foward riffed on what the “right” actions would be for Dayotn Public Schools.

“Right-sizing is keeping our promise to every child and parent in this district to guarantee a quality equitable education. Right-sizing is placing effective, professional leaders in every building, who know how to develop teachers and implement systems to promote student achievement,” Foward said.

“Right-sizing is showing respect for the teaching profession to hire people who are knowledgeable, caring and capable of making certain every child grows to the next level after 10 months of school,” he continued. “Right-sizing is guaranteeing that every class in every building has a teacher from the first day to the last day of school. Right-sizing is making right choices for all students no matter their zip code, socioeconomic status, creed and their culture.”

The first of two open community meetings to discuss potential school closures is scheduled for 6 p.m. Thursday at Meadowdale PreK-6 School, 3871 Yellowstone Ave. Acting Superintendent Elizabeth Lolli said earlier Tuesday that she hopes to recommend a school facilities plan to the school board in the coming weeks, in hopes that the board can make a decision for 2018-19 at its March 20 meeting.
