The 31-year-old striker arrived at Dean Court in a £4million deadline day move from Premier League rivals Crystal Palace and brings with him a real goalscoring nous according to the boss.
"Glenn did incredibly well for Crystal Palace at the end of last season and was pivotal to them staying in the division," Howe told the Daily Echo.
"He is a player we have liked for a long time and he made an impression playing against us at Burnley during his Championship days. He made the step up to the Premier League and did very well last season with some very good performances.
"He will add a different dimension to our attack and to our frontline. He is very good with crosses, very good aerially and a real goal threat.
"Glenn is an out-and-out number nine. He thrives on being in the box and scoring goals and does it very well. His record in terms of goals to games is second to none.
"You need more than one number nine and we need competition for places in all areas of the squad. I felt we were a little light in terms of options in our frontline.
"Glenn adds several options in terms of partnerships and what we want to do in that area of the pitch. In this league, you need goals from more than just one player and we are delighted to bring him in."
